The 22-day Sherpani Col Pass Trek is not a conventional trekking holiday. It is a technical, high-altitude expedition-style traverse connecting the Makalu-Barun region with the upper Khumbu by crossing Sherpani Col, West Col and Amphu Lapcha.
The approach follows the Makalu Base Camp trail from Num through Seduwa, Tashigaon, Khongma Danda, the Shipton La system and the Barun Valley. Beyond Makalu Base Camp, the route enters an uninhabited glacial world through Swiss Base Camp and Sherpani Col Base Camp before crossing two passes above 6,000 m toward the Hongu Basin. The final technical barrier, Amphu Lapcha, leads to Chhukung and
the Everest trail.
Participants must be experienced, exceptionally fit and comfortable using crampons, harnesses, ascenders, descenders, fixed ropes and ice axes. Snow slopes, crevasses, glacier travel, rockfall, avalanche exposure and long summit-length days are real hazards. Route success is never guaranteed, and the climbing leader may delay, change or abandon a crossing.
Eastern Nepal rewards prepared trekkers with long approaches, remote settlements and exceptionally varied Himalayan terrain. The experience is less commercial than Nepal’s busiest trekking corridors, but that also means simpler facilities, longer logistics and fewer alternatives when weather or transport changes. The itinerary therefore emphasizes self-sufficiency, gradual altitude gain, experienced local leadership and enough flexibility to protect both safety and route integrity.
The planned route unfolds in distinct stages: Fly from Kathmandu to Tumlingtar and Drive to Num; Acclimatization at Khongma Danda; Trek from Langmale Kharka to Makalu Base Camp; Cross West Col and Enter the Upper Hongu Basin; Trek from Tengboche to Namche Bazaar; and finally Final Departure. These are the main stages of the programme rather than a promise of fixed daily timings. The detailed itinerary gives the daily walking or transfer descriptions, accommodation arrangements, altitude notes and adjustments that may be needed in practice.
Road and flight times are approximate. Weather, landslides, road conditions, aircraft schedules and local access can change the starting point or timing.
An expedition-grade traverse requiring glacier travel, fixed-rope skills and crossings of Sherpani Col, West Col and Amphu Lapcha. Participants need previous mountaineering experience and excellent fitness. Multiple acclimatization stages and guide-led health checks are mandatory. Technical crossings proceed only when health, snow, glacier and weather conditions are acceptable.
Mountain weather can change rapidly. Rain, snow, wind, river conditions and freezing nights may affect high passes and remote camps even in the preferred seasons.
A licensed guide manages route decisions, permits, accommodation or camps, altitude monitoring and emergencies. Porter or pack support and baggage limits depend on the package and terrain.
Makalu Barun and Sagarmatha protected-area permits, current trek registration and any route-specific authorisation will be confirmed for the final expedition itinerary.
Insurance is mandatory and must cover the route’s maximum altitude, trekking or technical activity, medical treatment, trip interruption and helicopter evacuation in Nepal. The guide coordinates first response, descent, ground transfer or helicopter evacuation. Rescue depends on weather, terrain, communications, aircraft availability and payment or insurer guarantees.
Respect local cultures and sacred sites, ask before photography, conserve water and fuel, minimise plastic, stay on approved routes and carry waste out.
Tumlingtar: approximately 410 m / 1,345 ft | Num: approximately 1,560 m / 5,118 ft | Flight: approximately 45–50 minutes | Drive: approximately 5–8 hours Fly to Tumlingtar when conditions permit and continue by rough mountain road through Khandbari toward Num. Mountain-road times are approximate and may increase because of traffic, roadworks, landslides, river conditions or seasonal damage.
Within the Arun and Barun valleys of eastern Nepal, where subtropical approaches gradually give way to remote alpine and glacial terrain, trail surfaces, bridge conditions and seasonal water levels can alter the pace. The guide will manage breaks and may modify the stopping point if weather or trail conditions, accommodation availability, or a participant’s health make the published schedule impractical.
Tashigaon: approximately 2,100 m / 6,890 ft | Trek: approximately 4–5 hours Walk through villages, cultivated hillsides and forest to Tashigaon, the last substantial permanent settlement before the higher route. Expect the effort to vary with altitude, temperature, trail condition and accumulated fatigue, even when the published hours appear moderate.
Khongma Danda: approximately 3,500–3,760 m / 11,483–12,336 ft | Trek: approximately 7–9 hours Climb steeply through rhododendron and cloud forest into alpine terrain. Conditions can range from forest shade or cultivated paths to open, wind-exposed slopes depending on the section.
A gentle walk or locally appropriate excursion supports acclimatization while introducing the Arun and Barun valleys of eastern Nepal, where subtropical approaches gradually give way to remote alpine and glacial terrain. The guide controls the height gain and return time, leaving the afternoon for hydration, equipment checks and recovery.
