Mount Pumori Expedition

Spring (March to May) and autumn (September to November) are the two reliable expedition windows, because the jet stream lifts above 8,000 m during both periods and gives stable summit weather. Spring brings warmer temperatures, longer days and better snow consolidation on the upper ridge; most Pumori expeditions target a late-April to mid-May summit. Autumn post-monsoon offers drier, colder air and excellent visibility, with less snow on the approach trail.

Winter (December to February) is viable only for fully self-sufficient, experienced teams prepared for extreme cold above 6,000 m. The summer monsoon (June to August) loads the upper mountain with fresh snow and whiteout conditions, making reliable summit attempts impractical. Swotah runs both spring and autumn departures.

Nepal's Department of Tourism charges approximately USD 2,000 per person for the Pumori climbing permit, payable before departure for the specific season and route. Sagarmatha National Park entry costs NPR 3,000 for non-SAARC nationals and is paid separately at the Monjo checkpoint. Swotah files all permit paperwork once you provide a passport copy and two passport photos; current rates are confirmed before your booking is finalised.

Nepal also assigns a Government Liaison Officer to each expedition at the Ministry of Tourism's request. Swotah handles the LO request and covers the LO's accommodation, kit allowance and salary as part of the expedition cost. The garbage deposit, refunded on clean departure from base camp, is also managed by Swotah.

The 11-day approach trek from Lukla gains altitude progressively before serious climbing begins. A rest day in Namche Bazaar at 3,440 m includes an acclimatisation walk to the Everest View Hotel at 3,800 m; a further rest day at Lobuche (4,940 m) and a final night at Gorakshep (5,170 m) prime the body before the climb to Base Camp at 5,300 m. This gives roughly three weeks of gradual altitude exposure.

The 17-day climbing period then uses multiple rotation cycles following the climb-high-sleep-low rule: Base Camp to Camp I (5,700 m) and return, then to Camp II (6,200 m) and back, before the full camp-by-camp ascent to Camp III (6,480 m) and the summit. Each rotation builds red blood cell count and lets the team assess individual acclimatisation. Buffer days within the block allow adjustment.

Food on the approach trek is teahouse cooking: dal bhat, noodles, potatoes, porridge and omelettes, with three meals per day included. Above Namche, menu range narrows and prices rise with altitude. At Base Camp, Swotah's cook team prepares high-calorie expedition meals: pasta, rice, soup, tinned fish, porridge and hot drinks throughout the day. High-camp provisions are pre-packed and lightweight, typically instant noodles, porridge, energy bars and hot drinks.

Drink 3 to 4 litres per day on the approach and at least 3 litres at altitude, because dehydration worsens altitude sickness. All water above Base Camp must be boiled or treated before drinking. Swotah provides boiled drinking water at Base Camp; carry purification tablets or a filter for the upper mountain.

The expedition starts with a 35-minute mountain flight from Kathmandu's Tribhuvan International Airport to Tenzing-Hillary Airport at Lukla (2,845 m). Lukla flights are weather-dependent and can be delayed for days in poor visibility; the itinerary includes a contingency day in Kathmandu and a second on the return leg. Swotah arranges domestic tickets and monitors forecasts.

A helicopter option from Kathmandu to Lukla or a higher landing zone is available at extra cost if the fixed-wing service is delayed beyond the contingency buffer. Kathmandu airport transfers use private vehicles. Expedition freight travels on the domestic flight, with overweight fees pre-agreed with the carrier.

The Southeast Ridge is the standard line on Pumori, first ascended by Lenser's 1962 team and now the established expedition route. From Base Camp at 5,300 m, the route crosses glacial terrain to Camp I at approximately 5,700 m over 40 to 50 degree snow with fixed rope on the steepest sections. Camp II sits at around 6,200 m above a crevasse zone on sustained ice up to 55 degrees.

Camp III at approximately 6,480 m is the summit-launch point, reached by ascending a 1,000 m wall of glacial blue ice at 50 to 70 degrees. From Camp III the ridge narrows to the summit at 7,161 m, with mixed rock steps near the top. The descent follows the same line with abseil stations on the technical sections. All ropes are fixed by the Swotah Sherpa team before the main expedition push.

Swotah assigns a climbing Sherpa as a personal high-altitude partner to each western climber for the technical sections and summit day. All Swotah climbing Sherpas hold Ministry of Tourism guide licences, have completed the Nepal Mountaineering Association's high-altitude training and carry at least three prior Himalayan 7,000 m summit credits. The base camp team includes a Base Camp Manager, expedition cook, kitchen assistant and the Ministry-assigned Liaison Officer.

Porter loads are capped at 25 kg on the approach and high-camp carries are managed by the Sherpa team at controlled weights. Swotah provides a free duffel bag for porter loads so climbers walk the Khumbu trail with a light daypack. Staff insurance, kit and fair wages are covered by Swotah; tipping guidelines are covered in the pre-departure briefing.

Pumori Base Camp at 5,300 m sits on a moraine shelf at the foot of the Southeast Ridge, a few hours above Gorakshep. The Swotah base camp has individual sleeping tents, a mess tent with tables and chairs, a cook tent, toilet tents and a communications tent. The advance team establishes the camp and stocks it before the main expedition group arrives.

High camps at 5,700 m (Camp I), 6,200 m (Camp II) and 6,480 m (Camp III) each use two to four two-person expedition tents pre-stocked with sleeping bags, stove and fuel. Climbers carry personal gear in lightweight summit packs. All high-camp waste is carried down to Base Camp and then out to Lukla; Nepal's clean-mountain regulations require it and the garbage deposit covers the disposal cost.

Mobile coverage on the Khumbu approach trail is consistent at the main villages: Lukla, Namche, Dingboche and Lobuche all have Nepal Telecom (NTC) and Ncell signals. Coverage becomes patchy above Gorakshep and is absent at Base Camp. Swotah provides a tourist SIM on arrival in Kathmandu.

At Base Camp the expedition uses a satellite phone and, when conditions allow, a satellite internet terminal for weather forecasts and daily check-ins with the Kathmandu office. Wi-Fi is available at tea houses on the approach for a fee. Above Lobuche bring a power bank or small solar charger; cold drains batteries overnight at altitude and mains power is unreliable above the main villages.
