Nar Phu branches off the main Annapurna Circuit road route near Chame into one of Nepal’s narrowest and most dramatic gorges, leading to two villages — Nar and Phu — that remained closed to trekkers until 2003 and still see only a small number of visitors each year. The valley’s isolation has preserved a distinct Tibetan Buddhist culture, visible in monasteries, chortens, and village architecture that feel noticeably different even from other high-altitude Nepali villages.
The trek’s return route crosses Kang La, a genuinely demanding 5,322m pass that rejoins the Annapurna Circuit trail at Ngawal — meaning Nar Phu can be trekked as a standalone loop or combined directly with an Annapurna Circuit itinerary for trekkers wanting an extended, more remote version of that classic route.
Because the valley requires its own restricted-area permit alongside the standard Annapurna paperwork, and the Kang La crossing demands solid trekking fitness, this is a trek best suited to experienced trekkers looking for one of Nepal’s least-visited restricted areas rather than a first Himalayan trip.
