Book 3 to 4 months ahead for an October trek, 2 to 3 months ahead for September, November or the March to April spring season, and 2 to 6 weeks ahead in winter or the monsoon. The early booking buys you Lukla seats, better teahouse rooms and the guide you want, not a cheaper trek, since agency prices barely move with the calendar. Late 2026 is a good time to book: after the August floods, every Swotah trek is running except the Tamang Heritage Trail, and Langtang reopened on 22 October 2026 via Thulo Syabru.

The question we hear from most prospective travellers is not "where should I go in Nepal?" but "when should I go, and when should I book?" The answer depends on a few key factors: the season you want to travel, the treks or experiences you have in mind, and how much flexibility you have on dates. Here is our honest guide to timing your Nepal trip.
The Best Times to Travel Nepal
Nepal has two primary trekking seasons:
Autumn: September to November
This is Nepal's golden window. The monsoon lifts in late September, leaving the sky crystal clear and the mountains brilliantly visible. October and November bring stable temperatures, dry trails, and maximum visibility. You genuinely see Everest, Annapurna, and Dhaulagiri from the trekking paths. Dashain and Tihar, Nepal's two largest festivals, usually fall in October and November, adding a cultural richness that makes this season extraordinary. In 2026 Dashain runs from 11 to 25 October, with the main Tika day on 21 October, and Tihar from 7 to 11 November.
The trade-off: this is also peak season. Popular routes like Everest Base Camp and Annapurna Circuit have more trekkers, and teahouse bookings fill up. If you want to trek in October, book your trip at least three to four months in advance.
Spring: March to May
Spring is Nepal's second-best trekking season and, for many trekkers, the more beautiful one. The rhododendron forests between 2,000 and 3,500 metres erupt in red, pink, and white from late March through April, a remarkable sight on the Annapurna Circuit and the trails around Ghorepani. Temperatures are comfortable, skies are mostly clear, and the landscape feels alive. Mount Everest climbing expeditions also depart in spring, so the high Khumbu is busy from April onwards.
Winter: December to February
Lower-altitude trekking and cultural tourism work beautifully in winter. Kathmandu, Pokhara, and the Chitwan jungle are all pleasant. The Annapurna Base Camp trek is doable for fit trekkers with proper gear, but snow and avalanche risk between Deurali (about 3,230 m) and Machhapuchhre Base Camp can close the upper trail for days at a time. High-altitude routes like EBC and Manaslu are very cold, and high passes such as the Larke La on Manaslu and the Thorong La on the Annapurna Circuit can be shut by snow. Winter is Nepal's quietest season. Teahouses are quiet, prices are lower, and you experience a more local, unhurried Nepal.
Monsoon: June to August
The monsoon is challenging for trekking in most of Nepal: leeches on lower trails, cloud cover obscuring mountain views, and occasional landslide-related road closures. However, this is when the Tibetan rain-shadow areas, Upper Mustang, Nar Phu, and Dolpo, come into their own. These high-plateau desert landscapes receive very little monsoon rain, which makes them some of the few good trekking choices from June to August. The roads and flights that reach them can still be hit by rain lower down, so leave a spare day at each end.
Is Now a Good Time to Book? Nepal in Late 2026
Yes. The floods of 26 August 2026 hit Rasuwa and the Langtang road hardest, and the questions we got for weeks were about whether to cancel. Most of the country was never affected. The Prithvi Highway between Kathmandu and Pokhara has been open since 17 September, the Everest and Annapurna regions run as normal, and Manaslu treks are running again, with a jeep to Machha Khola after the Arughat Bailey bridge reopened on 18 October.
Langtang, Kyanjin Gompa and Gosaikunda reopened on 22 October 2026, with Thulo Syabru as the new trailhead. Swotah's four Langtang treks are rerouted and running. The one trip still paused is the Tamang Heritage Trail, because the villages of Timure, Briddim and Gatlang remain cut off. The road to the Rasuwagadhi border with Tibet is closed, so Tibet tours fly to Lhasa for now.
Conditions change, so check the Swotah travel updates page before you fix dates. Our flood trekking update covers each route, and why visiting after the flood helps explains what a booking does for the guides, porters and lodge owners who depend on the autumn season.
How Far in Advance Should You Book?
- Autumn travel: Book 3–4 months ahead for October, 2 months for September or November.
- Spring travel: Book 2–3 months ahead, especially if you want peak April dates.
- Winter and monsoon travel: 4–6 weeks' notice is usually sufficient, though restricted-area permits (Upper Mustang, Manaslu) have processing time that requires more lead time.
Recommended Booking Lead Time by Season
The weeks below follow the advice in this guide. They are the earliest end of each range, which is what we suggest if you have a fixed date or want a particular trek.
| Travel month | Book ahead | Lead time |
|---|---|---|
| October | 16 weeks | |
| April | 12 weeks | |
| March, May | 9 weeks | |
| September, November | 9 weeks | |
| December to February | 6 weeks | |
| June to August | 6 weeks |
What Affects Pricing?
Nepal trekking costs are relatively stable year-round. Your accommodation, permits, and guide fees don't fluctuate with seasons the way European city breaks do. What does fluctuate is international airfare. The cheapest flights to Kathmandu are usually found 2–4 months ahead. Booking in the 10-day window before departure typically results in significantly higher airfares. If you are flexible on exact dates, check fares across a week's window for the lowest options.
Booking Lead Times at a Glance
| What you're booking | Book ahead by | Why |
|---|---|---|
| Peak-season EBC or ABC trek (Oct–Nov, Mar–Apr) | 8–12 weeks | Lukla/Manthali flights and good teahouses fill first |
| Restricted areas (Mustang, Manaslu, Dolpo) | 4+ weeks | Restricted-area permits are processed through an agency in advance |
| Travel around Dashain–Tihar (Oct–Nov) | 2–3 months for domestic flights | The whole country travels home for the festivals |
| Offseason trips (monsoon, winter) | 2–4 weeks | Availability is easy; weather buffers matter more than bookings |
| Bhutan add-on | 6–8 weeks | Visa clearance and the Sustainable Development Fee (USD 100 per adult per night until 31 August 2027) are usually handled through your operator |
For Everest in October, November, March and April, most Lukla flights leave from Manthali (Ramechhap), a 4 to 5 hour drive from Kathmandu, instead of Kathmandu airport. That is one more reason to book the trek and the flight together, early.
Key Dates for 2026 and 2027
| Date | Event | What it means for your booking |
|---|---|---|
| 11 to 25 Oct 2026 (Tika 21 Oct) | Dashain | Buses and domestic flights fill as people travel home |
| 26 to 28 Oct 2026 | Mani Rimdu, Tengboche | Busy lodges around Tengboche on the EBC trail |
| 7 to 11 Nov 2026 (Laxmi Puja 8 Nov) | Tihar | Lit-up towns, some offices and shops close |
| 15 Nov 2026 | Chhath (main evening) | Mostly the Terai, a public holiday |
| 6 Mar 2027 | Maha Shivaratri | Huge crowds at Pashupatinath |
| About 21 to 22 Mar 2027 | Holi | Hills a day before the Terai, expect paint |
| About 10 to 18 Apr 2027 | Bisket Jatra, Bhaktapur | Peak spring season, book Bhaktapur hotels early |
| 20 May 2027 | Buddha Jayanti | Lumbini, Boudhanath and Swayambhunath at their busiest |
Two calendars worth checking before you fix dates: the 2026/2027 festival dates, which can be the highlight of a trip or the reason your bus is full, and the offseason guide if your dates fall outside the classic windows.
When Booking Early Saves Money (and When It Doesn't)
Nepal is not the airline industry: trek prices from reputable agencies barely move with the calendar, so booking early buys availability rather than discounts. What early booking really gets you is the good stuff that runs out: rooms with attached bathrooms in Namche, the better guides (the best are reserved months out for October), and seats on the Lukla flights you actually want. Late booking, by contrast, genuinely pays in the offseason. From December to February and June to August you can assemble a trek a week out and negotiate room quality upgrades on the trail itself.
What You Can Realistically Book Last-Minute
Landing in Kathmandu without a plan still works for some trips. City sightseeing, Pokhara, and Chitwan run year-round on a few days' notice. Short Annapurna treks (Poon Hill, Mardi Himal) can usually be arranged within two or three days in any season, since the permits are issued the same day and the trailheads are road-accessible. You will still need a licensed guide, which has been required on most trekking routes since 1 April 2023, and an agency can set that up in a day or two. What does not work last-minute: peak-season Everest trips (the flight is the bottleneck), anything in a restricted area (Mustang, Manaslu, Dolpo permits take time and an agency), and travel during the Dashain-Tihar window, when the whole country is on the move. Our guides to choosing a trek and choosing an agency shorten the decision once your dates exist.
Deposits, Balance and Cancellation with Swotah
Booking early with Swotah does not tie up your money. A deposit from 10% of the trip cost holds your place, and the balance is due 15 days before departure. If you cancel more than 150 days out, up to 90% is refunded, with smaller refunds closer to the date. You can reschedule up to 30 days before departure, subject to availability, and transfer your booking to someone else up to 15 days before. Permits, flights and insurance bought for you are third-party costs and are not refunded. Card payments carry a 3.65% bank charge. The full refund table is on the booking and cancellation page, and that page is the one that applies.
Trips to Book for the Coming Seasons

The Bottom Line
There is no bad time to visit Nepal, only times that are better suited to particular experiences. If mountain views and trekking are your priority, autumn or spring. If culture and lower-altitude exploration suit you, winter is wonderfully quiet. If you want the most remote Himalayan experience, the rain-shadow valleys await you in monsoon.

Frequently Asked Questions
How far in advance should I book a trek in Nepal?
For October, book 3 to 4 months ahead. For September, November and the March to April spring season, 2 to 3 months is enough for most treks. In winter and the monsoon, 2 to 6 weeks usually works, but restricted areas such as Upper Mustang, Manaslu and Dolpo need at least 4 weeks for permits.
Is it cheaper to book a Nepal trek early?
Rarely. Agency trek prices barely change through the year, so booking early mostly buys availability: Lukla seats, rooms with attached bathrooms in places like Namche, and the more experienced guides. International flights to Kathmandu are the part that gets cheaper, usually 2 to 4 months before departure.
Is it safe to book a trip to Nepal after the 2026 floods?
Yes, for nearly every route. The Everest and Annapurna regions were not affected, Manaslu is running again, and Langtang reopened on 22 October 2026 via Thulo Syabru. Swotah has paused only the Tamang Heritage Trail. Check the travel updates page before you travel.
What is the best month to visit Nepal?
October, for clear mountain views and dry trails, followed closely by November and April. If you want quiet trails and don't mind the cold, December and January work well below about 4,000 m. June to August suits Upper Mustang and the other rain-shadow valleys.
How much deposit does Swotah need?
From 10% of the trip cost, with the balance due 15 days before departure. Cancellation more than 150 days out refunds up to 90%, and you can reschedule up to 30 days before. The booking and cancellation page has the full terms.
