Nar Phu Valley and Mesokanto Pass Trek - 18 Days

Two Valleys, Three Passes

The trek can be split into three distinct phases:

• Phase 1 (Days 4-9): Nar Phu approach and exploration. Walk from Koto into the canyon, visit Phu (the higher village), descend to Nar (the lower village), rest day, then cross Kangla into the Annapurna Circuit.
• Phase 2 (Days 10-13): Annapurna Circuit section. Walk via Manang and Khangsar to Tilicho Lake. Stand at the highest large lake on Earth.
• Phase 3 (Days 14-16): Mesokanto Pass exit. Cross the rarely-walked Mesokanto La and descend to Jomsom. Camping above 4,500m.

Nar and Phu Villages

The fortified Tibetan-Buddhist villages of Nar and Phu were closed to outsiders until 2002. They retain a medieval feel - stone houses clustered around a central monastery, painted chortens, prayer flags everywhere. Phu sits at 4,240m and is famously inhospitable in winter; Nar at 4,120m is slightly more sheltered. The local language is Nar-Phu dialect of Tibetan.

Tilicho Lake

At 4,919m, Tilicho Lake is one of the highest lakes in the world (the title of "world's highest" is disputed, but it is the highest of significant size). The lake fills a glacial basin with a turquoise mineral-stained surface that reflects the surrounding ice cliffs.

The Three Passes

• Kangla Pass (5,322m): The connection between Nar Phu and the main Annapurna Circuit. Snow-covered most of the year.
• Tilicho Lake (4,919m): Not a pass technically, but a high-altitude day trip from Khangsar.
• Mesokanto La (5,340m): The exit pass from Tilicho into the Kali Gandaki valley. Rarely crossed - most trekkers descend back the way they came.

Acclimatisation

Rest day at Phu (Day 7) plus a steady climb profile gives a good acclimatisation arc. The Kangla crossing on Day 11 comes after multiple nights above 4,000m. Mesokanto on Day 16 follows several days above 4,500m.

Permits

• Annapurna Conservation Area Permit (ACAP)
• Nar Phu Restricted Area Permit (USD 75-100 first week + USD 10-15/day after)

Restricted-area permit requires minimum two trekkers and licensed guide.

Best Season

• Spring (April-June): Warmer pass conditions, dry
• Autumn (September-October): Clearest views, drier

Summer (July-August) possible due to rain shadow. Winter impossible.
