Chulu East Peak Climbing

The two climbing windows for Chulu East are the pre-monsoon spring (late March to late May) and post-monsoon autumn (October to early November). Both windows align with stable high-pressure systems that keep summit-day winds manageable and the snowpack consolidated.

Spring is the most popular time. March and April bring cold but clear mornings, with rhododendron in bloom on the lower approach, and the snowpack on the upper mountain is firm for crampon travel. Late May is warmer but afternoon cloud builds earlier. Autumn, from October into early November, offers the clearest skies of the year after the monsoon, cold but settled nights and excellent visibility from the summit. November works for the approach but the high camp becomes very cold, and Thorong La can see early winter snowfall. Avoid the monsoon season (June to September): the lower Annapurna Circuit trail floods and landslide risk rises, and the high-camp snow becomes unstable wet snow.

Chulu East sits within the Annapurna Conservation Area and requires three separate permits: the Annapurna Conservation Area Permit (ACAP, NPR 3,000 for non-SAARC), the Trekkers' Information Management System card (TIMS, NPR 2,000 for non-SAARC guided trekkers), and the Nepal Mountaineering Association (NMA) Group B peak permit for Chulu East. The NMA peak permit is the most significant cost: approximately USD 250 per person in spring (March to May) and a different rate in autumn; confirm current NMA rates with Swotah before booking as the NMA revises fees annually.

As a Group B peak, Chulu East requires the booking to be made through a registered trekking agency and the climbing guide must hold a valid NMA guide licence. Swotah arranges all three permits once you provide a passport copy and photos, confirms the current NMA rate, and keeps copies of the permit documents for the checkpoint inspections between Besisahar and Manang. Attempting the peak without the NMA permit carries a heavy fine.

Accommodation changes character three times across this 21-day trip. In Kathmandu and Pokhara, Swotah uses comfortable three-star hotels with private bathrooms, Wi-Fi and restaurant. On the Annapurna Circuit approach from Jagat to Manang and on the exit through Muktinath, Tatopani and Ghorepani, the accommodation is teahouse lodges: most have hot showers and varied menus in the main villages, though the stops above Pisang and around Thorong Phedi are more basic.

At Chulu Base Camp (approx. 4,800 m) and High Camp (approx. 5,500 m) the accommodation is tents. Swotah provides the camp equipment: high-altitude sleeping tents, a dining tent and kitchen tent. A four-season sleeping bag rated to at least -20 C is essential for the high camps, where overnight temperatures regularly fall below -15 C in spring and autumn. You carry a light daypack on the approach; Swotah provides a porter duffel for the main load.

Food on the Annapurna Circuit approach is standard teahouse cooking: dal bhat, pasta, noodles, eggs, Tibetan bread and momos, with dal bhat free on refill at most lodges and a varied menu through the main Annapurna Circuit stops. Above Manang the menu thins. At Chulu Base Camp and High Camp the cook prepares hot meals, porridge, soup and rice. Swotah includes all meals from the trek start to the return to Pokhara.

Water discipline is critical above 4,000 m: aim for 4 litres per day to reduce AMS risk. At teahouses, boiled water is sold or included; carry purification tablets or a filter for the camp sections where stream water is the only source. Do not drink untreated glacial meltwater. Electrolyte sachets help on summit day. In Kathmandu and Pokhara, bottled water and restaurants are widely available.

The trip starts with a drive from Kathmandu to Jagat (1,330 m), the trailhead on the Marsyangdi River. The road journey takes approximately 7 to 8 hours by private jeep via Besisahar and the rough lower Marsyangdi valley road, which is subject to landslide delays in wet conditions. Swotah uses private jeeps rather than buses for this section because the road is poor and a jeep handles the terrain better.

The exit from the Annapurna Circuit runs south from Ghorepani to the road at Nayapul, then by jeep or bus to Pokhara (approximately 2 hours), followed by a tourist bus or flight to Kathmandu on day 19. Flight is optional and costs extra; Swotah confirms the transport plan at briefing. Both the approach and exit legs can be affected by mountain road conditions, so the itinerary is designed with that flexibility built in.

The technical section of Chulu East runs from Chulu Base Camp (approx. 4,800 m) over three days: an approach to High Camp (approx. 5,500 m) on day 9, summit day on day 10, and descent back to Manang on day 11. The High Camp push crosses steep moraine, boulder fields and snow slope; crampons and ice axe are in use from the snowline.

Summit day starts at 2:00 to 3:00 am. The route ascends a mixed snow-and-rock ridge, traverses broken glacier and finishes up a steep (40 to 50 degree) snow face with fixed rope on the final 200 m. The summit at 6,584 m sits on a narrow rocky crest with an unobstructed panorama: Annapurna II (7,937 m) and Annapurna IV (7,525 m) fill the south, Gangapurna (7,455 m) and Glacier Dome (7,193 m) to the west, Manaslu (8,163 m) to the east, and Dhaulagiri (8,167 m) on the far horizon. The descent to Base Camp takes 5 to 7 hours from the top. Weather conditions, snow state and client fitness can alter the route, and Swotah's NMA-licensed climbing guide makes the final go or no-go call on summit night.

The Thorong La at 5,416 m is the high point of the Annapurna Circuit section and the second major altitude challenge of the trip, crossed on day 14 from Thorong Phedi (4,420 m) to Muktinath (3,800 m). It is a 15 km crossing of roughly 9 to 10 hours: 1,000 m of ascent on a well-worn trail to the prayer-flag-hung pass, then a long, steep descent of 1,600 m to Muktinath.

The Thorong La is not technical: no crampons are required in normal conditions, though October and early November can see ice on the ascent. The real demands are altitude (over 5,400 m) and stamina after the already-demanding climb to Chulu East summit four days earlier. The early start (4:00 to 5:00 am from Thorong Phedi) is important to avoid afternoon wind and cloud on the pass. Muktinath (3,800 m), one of the most sacred Hindu and Buddhist pilgrimage sites in the Himalayas, is the reward on the far side.

Chulu East requires an NMA-licensed climbing guide, not just a trekking guide: the peak permit is issued only to groups using a licensed agency with a qualified climbing guide on the team. Swotah's climbing guides hold NMA certification, have summited Chulu East and other Group B peaks, and carry a first-aid kit, pulse oximeter, supplemental oxygen for emergency use, and emergency communication gear.

A porter carries the main duffel on the Annapurna Circuit approach, capped at 20 to 25 kg, and a high-altitude porter carries the camp equipment above Base Camp. Swotah provides duffel bags, porter insurance and fair loads. A Gamow bag (portable hyperbaric chamber) is available at the Manang aid post, and the helicopter evacuation pad at Manang is the fastest route to lower altitude in an emergency. Comprehensive travel insurance covering emergency helicopter evacuation and rescue to at least USD 100,000 is mandatory for all climbers.

Mobile coverage on the Annapurna Circuit is better than on most Nepal treks but still patchy above Manang. Nepal Telecom (NTC) gives the strongest signal through the main Marsyangdi valley and in Manang itself; above the Thorong La in the Mustang valley, Ncell works in Muktinath. At Chulu Base Camp and High Camp there is no reliable mobile signal. Swotah provides a tourist SIM on arrival.

Wi-Fi is available at lodges in the main Circuit villages (Manang, Pisang, Chame) for a fee, and electricity for charging costs a few rupees per device at teahouses, rising above 4,000 m. Bring a power bank with enough capacity for summit day; cold temperatures at High Camp drain lithium batteries fast, so keep the power bank in a sleeping-bag pocket overnight. Solar panels at Base Camp can supplement charging if conditions allow.

Responsible practice matters on a peak permit climb. Carry all waste off the mountain: there is no rubbish collection above Manang, and the NMA increasingly monitors high-camp conditions. Use a reusable bottle and treat water rather than buying single-use plastic above Besisahar. Respect the Manangi communities and their Buddhist traditions, including the gompas at Manang and the sacred site at Muktinath.

Tipping is customary: a standard guideline is USD 15 to 20 per day for the climbing guide and USD 8 to 12 per day for the porter, paid in cash at the end of the trip. Swotah staff are paid fair wages and insured; the tip is a bonus for hard work at altitude, not a substitute for a living wage. Booking through a registered operator also ensures the NMA permit, staff insurance and proper porter loads are handled correctly.
