Nar Phu Valley Trek

A valley that was closed until 2002

Nar and Phu sit in a side valley off the Annapurna Circuit that was sealed to foreigners for reasons of border sensitivity until 2002. Two decades later it is open, but only under a restricted-area permit, and the practical result is that a trail two days' walk from one of the busiest routes in Nepal carries almost no one.

What is up there is not a scenic substitute for the Circuit. It is a pair of Tibetan-culture villages at over 4,000 m — Phu at 4,080 m under the ruins of a hilltop fortress, Nar at 4,110 m behind a row of chortens — that have kept a way of life the main valley largely traded away. Yak herding, barley, salt-route memory, and a working monastery that sees a handful of visitors a week.

The permit rules, and why they decide your trip

This matters before anything else, because the rules are not negotiable and they catch people out.

Rule	What it means for you
Restricted Area Permit required	Issued only through a registered Nepali agency — you cannot buy one yourself
No minimum party size	Since March 2026 a solo trekker can be permitted individually
Licensed guide mandatory	Not a recommendation here; a condition of the permit
Fee varies by season	Higher in the September–November window than the rest of the year
ACAP also required	The valley sits inside the Annapurna Conservation Area
Permit is date-bound	Issued for specific dates; changing them means re-issuing

We handle all of it, and the cost of both permits is in the price. The one thing we cannot solve is the minimum party size — if you are travelling alone, tell us early and we will try to place you on an existing departure rather than leave you to discover the rule at the permit office.

Be sceptical of any operator quoting you a solo Nar Phu trek. Either they are joining you to a group without saying so, or the permit is not what they claim.

How hard it is, and the two things that make it so

Challenging. Not technical — there is no rope, no crampons and no climbing — but two factors raise this well above a standard teahouse trek.

Altitude. You sleep above 3,500 m from day four and above 4,000 m for three consecutive nights, then cross a 5,320 m pass. That is a serious profile and the reason day seven exists as a rest day at Phu rather than a sightseeing extra.

The pass itself. Kang La is a long morning: a pre-dawn start, a sustained climb on scree and, in early or late season, snow. The descent on the Manang side is steep and loose. It is the hardest single day and everything before it is preparation for it.

A note on the height of Kang La

You will see Kang La listed as 5,416 m on a number of trekking sites. That is the height of Thorong La, copied across in error. The Nar Phu Kang La is 5,320 m. It is a small thing, but an operator who has not noticed it has not checked their own page.

The gorge, and what the walking is actually like

The approach from Koto is not a valley walk. The Phu Khola runs through a deep, narrow gorge and the trail is cut into the cliff above it, crossing and re-crossing on suspension bridges, with sections of exposed path and a good deal of noise from the river below.

It is dramatic and it is genuinely narrow in places. It is also completely manageable if you are steady on your feet and not badly affected by exposure. If heights trouble you, say so and your guide will position accordingly — this is one of the few Nepali trails where that is a real conversation rather than a formality.

Above the gorge the country changes entirely: the trees stop, the valley opens, and you are in dry high-altitude terrain that looks and feels like Tibet, because geographically it very nearly is.

Phu, Nar, and the days that are not about walking

Phu is reached on day six and you stay two nights. The village sits below a ruined fortress — a reminder that this valley controlled a trade route and needed defending. Below it is Tashi Lhakhang Gompa, a working monastery in one of the remotest inhabited settings in Nepal, where a visit means sitting quietly rather than touring.

Nar is a half-day's walk on and feels different — more agricultural, four gompas, a long approach past a line of chortens that is the most photographed thing in the valley for good reason.

The acclimatisation day at Phu is not padding. It is the day that decides whether Kang La goes well, and we use it to walk high and come back down.

Adding the Annapurna Circuit

Kang La drops you into Ngawal, which is on the Annapurna Circuit trail a day short of Manang. That makes this trek a natural front end to the Circuit rather than a detour from it.

The combined trip runs to about seventeen or eighteen days and crosses two passes over 5,300 m, with the Nar Phu section doubling as acclimatisation for Thorong La. It is the best version of the Annapurna Circuit available, and if you have the time we would encourage it over either trek alone — see the Annapurna Circuit with Tilicho Lake for what the second half looks like, and ask us to price the two together.

Lodges at 4,000 m

Basic and few. Nar and Phu have simple community-run lodges and homestays; Meta and Kyang have a handful of rooms between them. Nothing up here has heating beyond the dining room stove, hot water is a bucket if it exists at all, and the menu is short.

Because capacity is genuinely limited and the season is compressed, we book. In October there is no slack in this valley.

Season

September to November is the main window: stable weather, Kang La usually clear of deep snow, and the villages fully inhabited. March to May works well and is quieter still, though the pass can hold snow into April.

Winter effectively closes the valley — Nar and Phu partially empty as families move lower, and Kang La becomes a mountaineering proposition rather than a trekking one. The monsoon is poor for the usual reasons plus one specific: the gorge section is rockfall-prone in heavy rain.
