The Nar Phu Valley Trek accesses one of Nepal’s most isolated restricted valleys — a hidden Tibetan-plateau enclave sealed off from the outside world until 2002. The villages of Nar and Phu, reached via the dramatic Kang La pass (5,320m), preserve pre-Buddhist Bon traditions and a way of life connected to the Tibetan plateau with almost no modern influence. The trek typically combines with the Annapurna Circuit for a comprehensive 18-day journey through the full range of Annapurna landscapes.
1. Nar Phu Restricted Area Permit: USD 90 per person per week (approximately USD 180 for the 18-day trek). This restricted area permit strictly limits visitor numbers to the Nar Phu valley and is essential for preserving the area’s unique cultural and ecological integrity. Green Horizon includes this in the package and manages the entire application process.
2. Annapurna Conservation Area Permit (ACAP): NPR 3,000 per person. Required for the Annapurna Circuit section from Ngawal to Jomsom. Included in the package.
3. TIMS Card: NPR 2,000 per person. Included in the package.
A licensed guide is legally mandatory for all trekkers in the Nar Phu restricted area. Our guide manages all checkpoints and permit documentation throughout the trek.
Spring (April–May) and Autumn (September–October) are the best seasons for the Nar Phu Valley Trek.
Spring offers stable weather, warming temperatures in the valley, and the best conditions for the Kang La Pass crossing. Autumn delivers clear skies and excellent visibility. The Nar Phu valley receives less monsoon precipitation than southern Nepal due to its sheltered northern position — some years allow trekking in late August or September.
Winter (December–March) closes the Kang La Pass with deep snow and is not recommended. The monsoon (June–August) brings significant rain and unstable conditions — not suitable for the pass crossing. April and October are generally considered the optimal windows for this route.
The Nar Phu Valley Trek is rated Hard. The two major pass crossings — Kang La (5,320 m) and Thorong La (5,416 m) — require sustained high-altitude effort and excellent fitness. The remote nature of the Nar Phu section limits emergency response options, making both preparation and careful health monitoring critical.
Daily walking times range from 4 to 9 hours on varied terrain. Prior high-altitude trekking experience above 4,500 m is strongly recommended. Trekkers should train for at least 4 months with weighted hikes and cardiovascular conditioning. See our Trip Difficulty Grades and Altitude Sickness Prevention guides for full preparation details.
Start a dedicated training programme at least eight to twelve weeks before departure. Long day hikes with a loaded pack are the single best preparation. Include stair climbing, running, and cycling to build a cardiovascular base. Yoga or core-strengthening exercises help with the balance demands of rocky terrain.
If you live at a low altitude, no amount of treadmill training fully prepares you for the physical sensation of thinning air at 5,000 metres, but aerobic fitness is still the best buffer you have.
Drink three to four litres of water per day throughout the trek. Reduce or eliminate alcohol. Eat well at every opportunity even when appetite diminishes at altitude. Do not push through symptoms of altitude sickness; listen to your body and your guide.
The Himalayan Rescue Association clinic in Manang offers free altitude consultations and is well worth attending. Discuss Diamox with your doctor before leaving home, as it is an effective prophylactic for many people.
There are no ATMs inside the Nar Phu Valley. There is one ATM in Chame, but it is unreliable. Withdraw sufficient Nepali rupees in Kathmandu before departure.
Budget approximately USD 25 to 40 per day on the trail for extras such as:
Bring a little extra for unexpected expenses. Small denomination rupee notes are appreciated in remote village shops.
The Thamel neighbourhood in Kathmandu has dozens of gear rental and sale shops. Sleeping bags, down jackets, trekking poles, crampons, and most other equipment can be rented for USD 1 to 3 per item per day.
Buy or borrow well-worn, comfortable trekking boots before you arrive; new boots on a long trek cause blisters that can end a trip prematurely. Quality gear makes a meaningful difference at altitude and in cold temperatures.
In Nar and Phu, dress modestly and ask permission before photographing people or religious sites. Remove shoes before entering monasteries and homes.
Walk clockwise around mani walls, chortens, and stupas. Accept offerings of butter tea or tsampa with both hands or the right hand only.
The villagers here are not accustomed to large numbers of tourists, and the relationship between visitor and local community is one that deserves care and reciprocal respect.
Nar Phu was completely closed until 2002 and trekker numbers remain very limited. The Bon Buddhist culture, ancient cave monasteries, and plateau landscape are genuinely unlike anything on Nepal’s main trekking routes.
The Kang La (5,320m) involves steep rocky terrain and potentially some snow or ice. It’s not a glacier crossing but crampons may be needed in early season. The guide will assess conditions.
Yes — the standard approach is via Koto on the Annapurna Circuit approach road, and exit is via the Kang La to Ngawal. The Annapurna Circuit integration is the most logical routing.
Bon is Tibet’s pre-Buddhist indigenous spiritual tradition. In Nar and Phu, Bon and Tibetan Buddhism have merged into a unique local practice with distinct monasteries, rituals, and iconography rarely seen elsewhere in Nepal.
USD 90 per week per person. Green Horizon Tours arranges the permit in Kathmandu before departure.
Very few — annual trekker numbers in Nar Phu are in the hundreds rather than the thousands that visit the main Annapurna Circuit. The valley is genuinely remote and uncrowded.
