Common questions about Nar-Phu
Direct answers from our Kathmandu operations team based on current field conditions.
What permits do I need for the Nar-Phu Valley trek?
Because Nar-Phu borders Tibet, it is designated as a restricted area requiring a special Restricted Area Permit (RAP) alongside the Annapurna Conservation Area Permit (ACAP) and a TIMS card. Our team in Kathmandu secures these permits in advance using your original passport and physical passport photos. You must trek with a licensed guide, as solo permits are not issued for this region.
What is the altitude range on the Nar-Phu trek?
The trek begins around 1,000 m in Koto, climbs through the fortified villages of Nar at 4,110 m and Phu at 4,080 m, and reaches its highest point at Kang La Pass, which sits at 5,306 m. We design our itineraries with gradual daily gains above 3,000 m to ensure proper acclimatization before crossing the pass. Please consult your physician regarding altitude sickness prophylaxis.
When is the best time of year to visit Nar-Phu?
The optimal trekking windows are March to May in the spring and September to November in the autumn. During these months, skies are typically clear and daytime temperatures at high altitudes remain above freezing, though nights drop well below zero. We advise against winter trekking due to heavy snow blocking Kang La Pass.
How difficult is the Nar-Phu Valley trek?
Nar-Phu is classified as a strenuous trek suitable only for experienced hikers with strong cardiovascular endurance. The route involves long walking days, remote terrain, and the demanding high-altitude crossing of Kang La Pass at 5,306 m. We require all participants to maintain a consistent cardio fitness routine for at least three months prior to departure.
Are there teahouses in Nar and Phu, or do we need to camp?
In recent years, basic community-run lodges and teahouses have opened in both Nar and Phu villages, meaning full camping gear is no longer strictly necessary unless you prefer it. Accommodations are very rustic with shared facilities and simple dal bhat menus, so we carry supplemental fresh food and kitchen supplies. We recommend bringing a four-season sleeping bag rated to -15 degrees Celsius.
How many days does the Nar-Phu trek take?
A standard Nar-Phu circuit combined with the Annapurna Circuit takes approximately 12 to 14 days starting and ending in Besisahar. We prefer a 14-day itinerary to allow sufficient rest days for acclimatization in Nar and Phu before attempting the pass. Contact our Kathmandu office for a detailed day-by-day route profile.
Overview
About Nar-Phu
Departing from the main Annapurna Circuit at Koto, we guide small teams up the remote gorges of the Nar and Phu valleys. This region remained closed to outsiders until 2002, preserving a medieval Tibetan culture that feels entirely untouched by the modernization visible in lower valleys. Stone fortress villages, ancient gompas, and high altitude pastures define this arid landscape, where the inhabitants continue their traditional nomadic lifestyle herding sheep and trading across the Tibetan border.
Because of its proximity to the Tibetan border, the Nar-Phu region is designated as a restricted area requiring a special Annapurna Conservation Area Permit and a restricted area permit with a minimum of two trekkers accompanied by a registered guide. Our routes culminate in the challenging crossing of the Kang La pass at 5,306 meters, offering commanding views of Annapurna II, Tilicho Peak, and the Pisang Peak massif before descending back into the Marsyangdi River valley.
We operate these technical treks during two distinct weather windows: the pre-monsoon months of March through May, and the post-monsoon period from October through November. Spring brings blooming rhododendrons in the lower forests and stable daytime temperatures, while autumn delivers crystal clear skies over the high Himalayan passes. Early preparation for high altitude endurance is essential given the sustained elevation above 3,500 meters throughout the traverse.
