10 days- Langtang Valley Trek

The Etymology of "Langtang” in Tibetan is that “Lang” means a type of long-haired bovine yak, and “Tang” translates to “Field” or “Trail.” The word  “Langtang” roughly translates to “Yak’s field” or “Yak’s plain". Langtang, also known as  Lamtang among locals, is a Himalayan valley located in the north-central part of Nepal, covering an area of 1,710 square kilometres (660 square miles). Langtang Valley, also famously known by its other powerful name, “Valley of Glaciers,” emphasizes the glacial moraines, ice fields, and U-shaped valleys carved by ancient and current glacial activity for centuries. 

Langtang Valley trek is one of the closest trekking destinations from the capital city, Kathmandu, and sits at an elevation between 1,500 meters (4,921 feet) and 4,000 meters (13,123 feet) above sea level. This out-and-back trek, which starts and ends on Syarubesi, takes about  7 to 12 days to complete and spans a distance of approximately 60 kilometres (37.28 miles).  Despite being part of Langtang National Park, it is surprisingly less crowded and commercialized than other trails and can be called an off-the-beaten path. However, this does not detract from its beauty; the number of visitors doesn’t define the valley’s allure.  

There is simply no identity of  Langtang without yak; a significant portion of the local economy comes from the cheese production and cheese factory at Kyanjin Gompa, and “The guardians”- the peaks of the Langtang —the Langtang Lirung ((7,227 meters), Yala Peak (5,520 meters), and Dorje Lakpa (6,966 meters)— of this region and the indigenous Tamang People.  These peaks of the Lantang are the epitome of resilience, which is an apt description for Langtang and its people.

 After the devastating earthquake in 2015 in Nepal, which wreaked havoc on the valley, the sheer determination and unwavering spirit of the locals have brought Langtang back from the brink of despair. The transformation from the once shattered landscape to a place of hope and renewal is a testament to the indomitable will, courage, perseverance, and unity of the Langtang people.

Langtang Valley, located near the border of Tibet, lies in the northern part of Nepal. This adventure is a 6-day out-and-back trek that starts and ends at a small village called Syabru Besi, just 120 kilometres (75 miles) from the capital, Kathmandu Valley. Following the trek itinerary, this trek starts on day three from Syabrubesi(1,460 meters / 4,790 feet), a gateway for several destinations and trekking routes to Lama Hotel (2,480 meters / 8,136 feet), a small settlement settled near the banks of Langtang valley and surrounded by dense forests of bamboo, oak, and rhododendron. 

Day four of the trek takes the trekkers closer to the most awaited section of this entire trek, the village of Langtang, which takes roughly 7 to 8 hours. The strong presence of Tibetan Bhusshism is felt and seen more than ever. The fifth day of the trek is a short trek of 5- 6 hours to Kyanjin Gompa( (3,430m), one of the highest points of the trek. Day 6 is all about acclimatization and exploring this area. The Seventh and eighth days of the trek are about retracing the same trail and reaching the Syabru Besi, which marks the end of the trek.

Langtang Trek Difficulty

Langtang Trek includes a continuous hike of 7-8 days and 6-7 hours on average above the elevation of 2500 meters, with the highest point being Kyanjin Gompa at 3,830 meters. The altitude may change if the trekkers choose to do side treks exceeding up to 4,984 meters. This change in elevation in a short period of time increases the risks of Altitude Sickness.

Even though the trails are well-marked and maintained, it doesn’t mean walking in the park. The trail includes a mix of forested trails, rocky and steep ascents, and descents, which can range from moderate to strenuous levels of physical exertion for 6-7 hours on average per day, which can be certainly difficult for first-time beginners. 

Weather in high-altitudes like the Langtang region can be unpredictable, with sudden rainfall and harsh climates approaching, which makes the trails slippery and raises issues like landslides. It is highly recommended that you have prior trekking experience in similar conditions. At least have 3 months of overall workouts and cardio, such as running, swimming, cycling, and other exercises. And have control over the lungs by doing breathing exercises.

Weather of Langtang Valley 

The weather in Langtang Valley varies throughout the year, significantly affecting trekking conditions and experiences. Each season—spring, monsoon, autumn, and winter—brings its own unique climate, influencing everything from visibility and trail conditions to wildlife sightings and temperature.

Spring (March to May) and autumn (September to November) are generally considered the best seasons for trekking in Langtang. They offer stable weather, clear skies, and moderate temperatures, making for a more enjoyable and comfortable trek. On the other hand, monsoon and winter treks can be challenging due to heavy rains, slippery trails, and cold conditions, though they do offer solitude for experienced trekkers. Below is a detailed look at how the weather impacts trekking in Langtang Valley across these seasons.

Spring

Spring in Nepal lasts from March to May, and it is one of the best times to and most preferred by locals, tourists, and wildlife. Spring is the time when nature awakens from its long slumber, painting the landscape with vibrant shades of red, pink, and white rhododendrons, the national flowers of the foothills. The countryside becomes alive with life as birds return from migration, and wildlife becomes more active during the breeding season. 

The temperature mostly ranges from 10°C to 20°C at lower altitudes and -5°C to 15°C at higher altitudes. This dry season with clear skies gives stable weather and unobstructed visibility of the Himalayas. The trails are usually dry, with occasional rain showers and moderate temperatures. The moderate temperatures provide comfortable trekking experiences without the risk of overheating or harsh cold.

This season also offers an opportunity to become a wildlife and nature enthusiast. Langtang National Park is home to diverse flora and fauna, including rare and elusive species. This season, preferred by wildlife, brings everyone out to the common playground. The chances of seeing elusive animals and birds are generally high around this season, although there is the possibility of crowds along the trekking trails. 

Monsoon

The monsoon in Nepal intersects with the Summer season, bringing an intense and sustained amount of rainfall throughout the country. This season lasts from June to August and is mainly beneficial for farmers, as they heavily depend on the rain for a good harvest and crop plantation. Similarly, it also brings travel disruptions, causing the potential risks of flooding and landslides during hikes or commutes. 

In addition, this season has the warmest temperature and humidity. The temperature ranges from 15°C to 30°C (59°F 86°F) in the Langtang region. Trekkers may experience slippery and rugged trails with leeches, bugs, and earthworms. The unstable weather and continuous downpours can add to the already treacherous path demands the trekkers who are experienced and have prior experience hiking in rainy seasons.

 On the lighter side, the washed-out lush green landscape, furious rivers and fierce waterfalls cascading down the hill can be witnessed. Moreover, the path becomes less trodden, giving trekkers the prospect of having the entire place to themselves, with no disturbance of human traffic. 

Autumn 

Trekkers and nature enthusiasts adore this tea house trek for countless reasons: stunning wildlife encounters of elusive species and immersive cultural experiences. This dry and stable season coincides with a significant Hindu festival, marking it as a favoured season amongst locals and tourists.

This season, which spans September to November, provides excellent visibility, low precipitation, and a comfortable temperature typically between 10°C and 20°C (50°F to 68°F) during the daytime. In lower regions, nighttime temperatures generally range from 5°C to 10°C (41°F to 50°F), while at higher elevations, they can drop to around 0°C to 5°C (32°F to 41°F).

Keep in mind that every pro has its cons; this season is also overcrowded by tourists, and the rise in the prices of accommodation and food is making this rejuvenation trekking experience a bit overwhelming and exhausting. 

Winter

Winter, which falls from early December to mid-February, is not regarded as the best season. It is usually considered the off-season for trekking, but a few trekkers still love it. This season is unique in its own way: the trails boast snow-covered foothills and peaks, with the beauty intensified by the contrast of snow. However, the trails do get slippery. One of the cons is the temperature, obviously! But it can be a pro for some who enjoy the cold and are adrenaline junkies. The daytime temperature can range between 5°C to 12°C, dropping to below freezing (-10°C to -15°C) at night. Simultaneously, the prices of food and accommodation can fall for the same reason. The valley is pretty much yours alone, serving as a private experience in the tranquil nature.

Trekking in winter requires careful footsteps and proper gear. This season is usually not recommended, as it comes with its own set of do-nots. Nevertheless, if you are to hike Langtang during the winter season, be extra careful with your packing and make sure you are not a beginner.

Langtang trek Permits

Trekker’s Information Management System (TIMS)

According to the Nepal Tourism Board (NTB), Trekking in Nepal requires a mandatory TIMS ( Trekker’s Information Management System) permit for all trekkers, including those opting to trek the Langtang Valley trek. The rule applies to everyone, whether solo or group, regardless of the number of days or the size of the group. This rule was enacted for the safety of the tourists and policy-making to streamline tourism in the country. Failure to follow this rule may result in an offence, and fines may be charged.

These are available after filling out an application and submitting the required documents to the websites of TAAN and NTB or giving the necessary documents for the Permits to a registered and trusted Travel Agency in Nepal, like Swotah Travel and Adventure. The cost of the permit depends on the number of trekkers. 

• TIMS Card (Individual Trekkers): NPR 2,000 (approximately USD 20)

• TIMS Card (Group Trekkers): NPR 1,000 (approximately USD 10)

However, changes in the exchange rate can occur, sometimes increasing or decreasing the dollar rate.

Generally, there are two types of (TIMS) permits, one in blue and one in green. A green TIMS card is required for the Langtang Valley trek. The blue ones are often for restricted areas like Upper Mustang and Manaslu. There is also the option for Electronic-TIMS ( E-TIMS), which is for convenience and efficiency. 

Langtang National Park permit

Langtang Valley has been part of the  Langtang National Park since 1976. To enter the first Himalayan park in Nepal, which protects the area’s unique bio-diversity and cultural heritage in its natural habitat, needs a permit called Langtang National Park Entry Permit. 

The costs of permits solely depend on the nationality of the trekkers. SAARC ( (South Asian Association for Regional Cooperation) countries have to pay almost half of the total price, i.e., around NPR 1,500 (USD 12.50) for each entry, And the NON-SAARC national has to pay NPR 3,000 (USD 25). Nevertheless, the fluctuation of the USD currency is normal.

The collected fees are used for the development, conservation, and betterment of Langtang National Park.These are also available from NTB or TAAN. However, it is advisable to stay up to date with the current rules and regulations or contact a trusted and registered travel agency like Swotah. 

Packing list for Langtang Valley Trek

The packing list can change based on the season in which you’re planning to commence the trek. The universal rule while packing for any trek is always to pack light and the right things.

Water during the Langtang Valley Trek 

Water is a critical need for the trek and human survival. It becomes more important while trekking in regions like Langtang Valley. The human body requires more water during trekking; an ideal measurement would be at least 3- 4 litres of water daily. The rise in elevation, dry air, and increased physical exertion cause the body to dehydrate quickly, which can exacerbate symptoms of altitude sickness.

Carrying a personal water bottle and strictly avoiding purchasing bottled water along the trail minimizes the environmental footprint while trekking in Nepal. Alternatively, opt for different options that are environmentally friendly, have less impact on the environment, and promote sustainable tourism. There are tons of water bottles available in the market, each with its own benefits and drawbacks.

1.  Waterbottle 

Hydro flask or Insulated stainless steel bottle: This corrosion-resistant and non-absorbent bottle can keep water cold for 24 hours and hot for 12 hours. It has a long lifespan and is free from harmful chemicals like BPA.

Collapsible Bottles of Platypus Softbottle: As the name says, this is a collapsible bottle that can be rolled up when empty. It is extraordinarily lightweight, convenient, and durable. 

Filtered Water Bottles( Life Straw): The bottle comes with an integrated filter system that is easy to use, eliminating the hassle of filtration, allowing the trekkers to drink directly from the streams and sources and saving plenty of time. 

Hydration Bladder( CamelBak): This simple camelback mechanism allows trekkers to sip water without stopping the trek, especially during ascents. It usually holds 2 to 3 litres of water and perfectly fits in hydration sleeves in trekking backpacks. 

2. Purification of water:

Since tap water or water from sources like rivers and streams is not safe for drinking without treatment, few methods are available for treating the water.

Boiled Water

A common, safe and reliable option available in tea houses and lodges along the Langtang Valley Trek.  Water can be stored in the trekking bottle for the next day’s hike. A small fee is associated with these economical and sustainable options, but they are safe and recommended for consumption, as natural water sources might be contaminated. 

Water Purification Tablets

A popular and convenient method for disinfecting water during hikes and treks. There is a simple mechanism behind it; they work by releasing chemicals such as iodine, chlorine or chlorine dioxide, which is responsible for killing bacteria, viruses and parasites present in untreated water.  One tablet per litre of water and a wait time of 30-60 minutes, depending on the water condition. 

Moreover, they are effective and slightly time-consuming, leaving a mild aftertaste of chlorine and iodine. 

Water Filters

 are another reliable method for purifying water on treks. Even so, trekkers do not have to carry pump filters; gravity filters are used for the Langtang Valley Trek. This trek is not commercialized, but that does not mean there are no basic amenities, and trekkers have to pull their inner Bear Grylls out. Straw Filters and Bottled Filters are fine for this trek.

Chemical Drops

This option is lightweight, effective, and has a long shelf life. Chlorine or Iodine drops are used to disinfect water by killing bacteria, viruses, and protozoa ( though less effective against cryptosporidium). Depending on the temperature and clarity, treatment requires 30 minutes to 2 hours and leaves a mild chlorine taste in the water. The taste can be neutralized by using vitamin C in the water. It is great for short-term use and emergencies. 

Accommodation during Langtang Trek

The Langtang Valley Trek offers different options, ranging from basic to standard. Tea houses in lower regions are standard, but as you ascend, the facilities are limited to the basic. The Local Authorities of Langtang National Park have allocated fixed prices for accommodation, USD 5-15 per night. However, in peak season, it may be expensive or impossible to find one. 

An ideal room will be clean and comfortable, with a bed ( single or twin), blanket, and pillow, and a communal or attached bedroom. Asia squat toilets are mostly common in Nepal; trekkers will have to hit that squat position quite often.

In higher regions, some tea houses may charge extra dollars for hot showers. However, if you choose a cold shower, it is free. A few dollars will also be spent on charging and WIFI facilities in the teahouses. 

Food in Langtang Valley Trek

In the midst of awe-inspiring mountains, away from the traces of polluted air, the air is crisp and pure. This cleansing hike cleanses your soul and gut. The food is untouched by any chemicals and pesticides. It's a chance to experiment with traditional Nepali cuisine in the quaint little village and bless your taste buds. If you’re not much of a risk-taker, there is always an alternative to fall back on.

Almost all of the cuisines are available on the menu, which is identical through out the trek.. Swotah has a policy of providing one item per meal, meaning three meals a day are included in the package. 

Dal Bhat is a balanced diet that can be eaten as many times as one likes at a single cost and keeps you full all day. Every Nepali's go-to option for lunch and dinner option every single day.Dal Bhat: Includes Steamed White Rice, Lentil soup with local spices, Mix fried Vegetable curry with spices, sautéed Geen leafy vegetables, Meat gravy (if you want), Pickle and Optional ( Papadum, Curd). 

The mouth-watering MO: MO, a type of dumpling filled with minced meat, spices and vegetable 

A popular Tibetan Bread, sweet and salty fried bread served with honey. 

If you’re not a fan of these heavenly dishes, you can always choose the usual pizza, spaghetti, pasta, noodles, pancakes, porridge, muesli, or bread, as there is a wide range of options for food, hot and cold beverages. However, we strongly suggest you explore popular items of this region, including Yak cheese. 

Is Langtang Valley Trek for families?

Parents' foremost concern is regarding the safety, accessibility and elevation of the trek. Children are inherently curious about new things. Exposure to new languages, cultures, and places helps children develop and become socially proficient. The trek is bestowed with nature and culture, magnificent landscapes, welcoming people, a rich heritage, and rare flora and fauna. Along with this, this trek is well maintained and doable by children above the age of eight with the right planning and team. Anyone below that age is prone to vulnerabilities easily. 

Is Langtang Valley Trek Safe for Women?

The Langtang Valley Trek is generally safe for women, but like any remote trek, it requires some careful planning and precautions. Nepal is a friendly place for tourists, and the paths in the Langtang region are well-travelled, with lots of teahouses where you can meet other hikers. However, because the trek can be physically demanding and goes through isolated areas, it's a good idea for women to trek in groups or with a guide from a reliable company, perhaps choosing a female guide for added comfort. It's also wise to keep in touch with friends or family about your location, avoid hiking alone late in the day, and carry a way to communicate in case of emergency.

Is  LGBTQ safe in Nepal?

Nepal is a progressive country in Asia, which can be concluded by the recognition and legalization of LGBTQ people and their marriage. On a societal level, there are no cases of hate done to people because of their sexuality and preference. However, Nepali society is not fond of Public displays of affection or anything intimate, not directed towards homosexuals but also heterosexuals. As long as there is no PDA involved, everything is fine. Even if there is a PDA, there won’t be anything extreme, maybe a few frowned faces. 

Young people are the largest population that is more open about this topic. Especially in big cities like Pokhara and Kathmandu, there are even exclusive LGBTQ-friendly clubs if you’re into nightlife. Hit the floor. This sums up the entire situation of the country, including this Langtang Valley trek.  Swotah Travel and Adventure is inclusive of all races, sexes, and sexualities and is a proud ally. 

Is there  Internet Connectivity in Langtang Valley Trek?

Humans and the internet are intertwined in a way, and they will always find their way to each other. Having said this, while technological detoxing, the foremost concern will always be regarding the internet connection. Yes, there is WIFI available in almost all teahouses along the trail.  Most of the teahouses provide Free WIFI, and some might cost extra bucks. The connection is most reliable on the lower altitudes.  However, there might be the problem of a slow or unstable internet connection in higher elevations, the reason being limited resources for many users. 

Alternatively, a mobile carrier is also an option for connectivity. 

Telecommunication

Nepal offers several well-established mobile carriers that have been serving the public for several decades. Nepal Telecom ( NT), Ncell, Smart Cell, and CG Telecom are all currently available on the market. Upon arrival at the Tribhuvan International  Airport, visitors may acquire SIM cards from dedicated booths/counters by completing a quick application form. Alternatively, SIM cards are also readily available at the local authorised shops scattered throughout the country. 

When it comes to choosing a mobile provider, Nepal Telecom (NTC) and NCell are arguably the most reliable and trusted among locals and tourists. These two companies stand out through their extensive coverage, dependable service and comprehensive package.  

 Nepal Telecom (NTC)

One of the oldest government-owned telecommunication providers, it provides both GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access service platform), broadband internet (ADSL, fibre), and International Calling Services. It has quite a reputation for reliable connectivity across Nepal’s diverse geography, from big cities to remote areas.  NTC has several tailored short-term and long-term designed for tourist, depending on their needs and stay. 

NTC runs on a spectrum of frequencies expanding from 3G, 4G, and 5G (trial basis). NTC's 900 MHz (3G) and 800 MHz (4G) spectrum bands are particularly responsible for long-range coverage and play a crucial role in providing mobile services in remote areas like Langtang Valley. These low frequencies penetrate mountains and valleys better. Bridging the communication gap between rural and urban areas helps promote and market eco tourism and digital services. 

• 1 GB per day for 7 days + 60 minutes  1000NRS

• 1 GB per day for 14days + 100 minutes = 1,500 NRS 

• 15-20 GB data for 30 days + 60 minutes = 2,000NRS

They have quite a flexible plan, offering both prepaid and postpaid mobile services that are affordable and suitable for tourists, including data for internet SMS voice calls. 

Ncell

One of the competitors to Nepal Telecom (NTC), it provides similar services using GSM technology. It supports 2G, 3G, and 4G LTE, and is expected to join the 5G rollout soon, as its competitor NTC. NTC and NCELL are healthy competitors in Nepal's market, always taking the chance to overtake each other.  They also offer service of mobile voice, data, international calls, SMS, and broadband services. As per the tourist feedback, NCELL has extensive coverage nationwide, though it works smoothly at lower altitudes and in major cities. Their marketing strategy caters to everyone, including tourists, offering exclusive data packages. 

1. 3-day pack: 3 GB data + 30 minutes of talk time for Rs. 290.
2. 7-day pack: 7 GB data + 70 minutes of talk time for Rs. 490.
3. 14-day pack: 14 GB data + 140 minutes of talk time for Rs. 980.
4. 28-day pack: 28 GB data + 280 minutes of talk time for Rs. 1470.
5. 30-day pack: 88 GB data + 888 minutes of talk time for Rs. 2888.

To sum up, the Nepal mobile carriers market is dominated by Nepal Telecom and Ncell, which are excellent in terms of coverage and services. Their healthy competition has led to improved service quality and more affordable pricing for the user.  It is advisable to carry both pocket-friendly SIMs, as the altitude seems to fluctuate from lower to higher and vice versa during this whole trek.  

Altitude Sickness in Langtang Valley Trek 

Altitude Sickness is caused by a hostile high environment factor that exceeds human biological adaptability. When there is a rapid ascent above 2500M, and there is little to no acclimatization, this results in a decrease in arterial oxygen saturation (SaO2) and an arterial partial pressure of oxygen (PaO2).  In an ideal scenario, AMS develops in healthy people after a few hours of ascent, and the symptoms resolve spontaneously after a few 18-36 hours without requiring to descend lower. The symptoms mostly coincide with those of a hangover and progressively get worse if the body gets inadequate acclimatization days and the ascent does not stop. Nevertheless, our entire itinerary is dedicated to the acclimatisation of this Langtang Valley Trek.

Altitude sickness is classified mainly by severity into three syndromes, starting from mild-medium to severe-life-threatening. The process of dissecting the symptoms is complex and really important. Nevertheless, no one knows your body better than yourselves. If the symptoms are going beyond mild and medium, descending is the better option. 

 Acute Mountain Sickness (AMS )/ High Altitude Cerebral Edema ( HACE)

This common syndrome occurs at an altitude of 2500m when there is a rapid ascent and no acclimatization. The symptoms vary and range across a spectrum. On the one end of the spectrum, there is AMS with Mild to Moderate Symptoms, and on the other end, there is HACE with severe symptoms. 

The symptoms often start with a headache, anorexia, nausea, vomiting, dizziness, and fatigue, similar to a Hangover, and develop into life-threatening High-Altitude Cerebral Edema (HACE)  in less than 1% of AMS cases, which is characterized by Loss of coordination ( ataxia ) and an altered state of consciousness due to the build-up of fluid in brain which causes swelling, leading to increased intracranial pressure. HACE occurs at an altitude of  3,500 meters (about 11,500 feet) and above and develops after 24-72 hours ideally. Hallucinations, irrational behaviour, changes in personality, and Severe headaches that are not relieved by standard pain medications are also the symptoms experienced during HAPE. 

HAPE High-Altitude Pulmonary Edema

A life-threatening condition that occurs in an individual who ascends too quickly. It typically begins at an elevation of 2500 meters (8,200 feet), with the risk significantly increasing above 3,000 meters (9,800 feet) and 4,000 meters (13,100 feet). The chances of getting HAPE are 0.5% to 15% in an individual, which is pretty rare in an ideal scenario. The likelihood of developing HAPE rises when the body does not have enough time to adjust to lower oxygen levels. The rapid ascent can lead to a buildup of fluid in the lungs, making it hard to breathe and posing a serious threat to life.

 HAPE can develop and worsen quickly, so it is imperative to recognize the symptoms at an early stage. Listen to your body.  These symptoms often include difficulty breathing (especially when at rest), a cough that may produce frothy or pink, blood-tinged sputum, Tightness in the chest, Extreme fatigue and weakness, bluish skin, lips, or nails due to lack of oxygen (called cyanosis), Rapid breathing, and heart rate.

Descending to a lower area and allowing the body to acclimatise are the most effective preventive measures. A few medications can also be helpful.

Preventative measures

Some people are prone to getting Altitude sickness quickly due to genetic factors and underlying health conditions. There are a few preventive measures : 

Acclimatization:

Acclimatization is a complex and not fully understood mechanism to minimize ( hypoxemia)  ( low level of oxygen in the body) and preserve cell function despite reduced PO2 ( Parietal Pressure of Oxygen). The process by which the body gradually adjusts to lower oxygen at higher altitudes by making physiological changes.  This mechanism is still a tad bit mysterious. Acclimatisation works in most of the cases. However, there are times when it does not work.  

In addition, Hydration in moderation is as crucial as everything else because dehydration exacerbates the symptoms of altitude sickness. Drinking 3 to 4 litres throughout the day while hiking is a must. Remember not to Overhydrate your body by excessively consuming fluid.

Strictly avoid the consumption of Alcohol and Sedatives as they can dehydrate the body, depress the central nervous system, slow down breathing, and impair cognitive function, which is the opposite of what we need.

Additional Information

The traditional local remedy for Altitude sickness is a soothing bowl of garlic and ginger soup. It is believed that garlic and ginger soup improve blood flow, oxygen, nausea, and digestion. Besides this, simply inhaling the smell of garlic and ginger does wonders.

 Furthermore, there are always conventional ( allopathic) medicines such as —Acetazolamide (Diamox), Dexamethasone, Ibuprofen, Paracetamol, and Nifedipine, which work in a relatively short manner of time. Our experienced and expert guides have taken a basic first-aid course as a part of their registration, and they also carry the aforementioned medicines in their first-aid bag.

Travel Insurance for the Langtang Valley Trek

Considering all the possible worst-case scenarios associated with trekking, it is advisable and safe to say that everyone should have health insurance when trekking in high-altitude areas. Like, Langtang region. 

Opting for travel insurance in places like Langtang can be beneficial. In remote regions,  where safety resources are miles away, travel insurance can cover medical emergencies, including or excluding helicopter evacuation.  It can help cover the costs of medical treatment and hospital stays, which can be extremely expensive without insurance. Additionally, travel insurance can assist with trip cancellations or interruptions due to unforeseen circumstances and personal emergencies and recover nonrefundable costs such as flight tickets, tour deposits, and accommodations booking.

When choosing travel insurance, it is important to select a policy that offers versatile coverages, exclusions, and limitations that meet the desired requirements of a trekker, such as World Nomads, InsurancemyTrip, and Allianz Global Assistance. 

 When completing the TIMS application form, you will need to include information about your insurance as well.
