Annapurna Circuit Trek with Nar Phu Valley

Permits for the Nar Phu Valley: What Changed in 2026

This is the section most trekking sites get wrong, so here it is with current accuracy.

Nar Phu is one of Nepal's officially restricted areas, and entering it requires the Restricted Area Permit (RAP): USD 100 per person for the first week between September and November, USD 75 per person per week from December to August, with extra days charged at roughly USD 15 per day in peak season. You also need the Annapurna Conservation Area Permit (ACAP) at NPR 3,000 for foreign nationals. TIMS is not required for restricted areas, whatever older websites tell you.

The big change: on March 22, 2026, Nepal's Department of Immigration removed the minimum-two-trekkers requirement for restricted areas. Solo travelers can now obtain the Nar Phu RAP. What has not changed is the guide rule: you must trek with a licensed guide through a registered agency, with no independent trekking permitted, and the permit itself can only be issued through a registered agency. Checkpoints at Koto and inside the valley verify papers.

When you book with Index Adventure, both permits and every piece of paperwork are handled by us and included in the price. Bring your passport (valid six months beyond travel), a copy, and passport photos. For the broader Annapurna permit picture, see the Annapurna Circuit permit guide.

How Difficult Is the Annapurna Circuit with Nar Phu Valley Trek?

This is a strenuous trek, and we grade it that way deliberately. The numbers tell the story: twelve walking days, two passes above 5,300 meters, eight nights sleeping above 3,500 meters, daily gains of 600 to 700 meters, and walking days of five to eight hours on rugged, sometimes exposed trail. The Kang La crossing is an eight-hour day starting at 4 a.m.; the Thorong La crossing is comparable. Between them, the Nar Phu section has stretches with no lodges at all, which is why packed lunches and self-sufficiency are part of the plan.

What makes it achievable is the structure: three rest days placed exactly where the body needs them, gradual daily gains, and the fact that crossing Kang La first makes Thorong La feel noticeably easier, the reverse of how most circuit trekkers experience it. You do not need mountaineering skills. You do need genuine fitness: train for two to three months with hill walking under a loaded pack and be comfortable with consecutive long days. Prior high-altitude experience helps but is not mandatory for fit, well-prepared trekkers. Read how difficult the Annapurna Circuit is as your baseline, then add two grades for the Nar Phu section, and follow the plan in how to prepare for the Annapurna Circuit Trek.

Kang La Pass: The Wild Crossing

Kang La, at 5,320 meters (17,454 feet), is the pass that connects the Nar valley to the upper Annapurna Circuit at Ngawal, and it is the emotional summit of the Nar Phu section even though Thorong La is technically higher. The climb from Nar gains over 1,200 meters on moraine and scree; the summit panorama takes in Annapurna II, Annapurna IV, Gangapurna, Tilicho Peak, and, on clear mornings, the ranges rolling toward Tibet. Unlike Thorong La, you will likely have it to yourselves. The descent to Ngawal is steep and loose in its upper third, where trekking poles and the crampons we carry in shoulder seasons earn their place. In deep winter the pass closes with snow, which is why our departures hold to the two main seasons.

Best Time for the Nar Phu Valley Trek

Autumn (September to November) and spring (March to May) are the prime windows, with October the single best month: stable weather, sharp skies over both passes, and warm walking days. Spring adds blooming rhododendron to the forested canyon between Koto and Meta and warmer nights in the high villages.

Nar Phu holds one genuine secret the main circuit does not: the valley sits in the Himalayan rain shadow, so even in monsoon (June to August) it receives relatively little rain, and experienced trekkers use those months for maximum solitude. The trade-offs are real: cloud cover on the approach through the canyon, a slippery trail lower down, and less reliable mountain views, so we recommend monsoon only for flexible, experienced trekkers. Winter (December to February) closes Kang La with snow and is not recommended. The month-by-month picture is the best time for the Annapurna Circuit and the weather and temperature guide.

Altitude, Acclimatization, and Safety

The altitude profile of this trek is serious: you sleep at 4,250 meters in Phu, cross 5,320 meters at Kang La, and cross 5,416 meters at Thorong La, with eight consecutive nights above 3,500 meters. Our safety architecture around that profile: two acclimatization days inside the valley (Phu and Nar) before the first pass, a third rest day in Manang before the second, daily gains held to 600 to 700 meters, guides trained in AMS recognition carrying a full medical kit and oximeter, nightly oxygen checks at altitude, and the standing rule that worsening symptoms mean descent, no exceptions, no summit worth a life. In Manang, the Himalayan Rescue Association clinic offers a professional altitude briefing we build into the rest day.

Know the early signs yourself: headache, nausea, appetite loss, and broken sleep. Report them early; caught early, altitude sickness is managed by rest or descent, and hidden, it becomes dangerous. Comprehensive insurance covering helicopter evacuation above 5,416 meters is mandatory, and the remoteness of Nar Phu makes it non-negotiable: there are no roads in the restricted valley, and evacuation means a helicopter. The deeper medical picture is in the altitude sickness guide, and for a sober look at risk on the wider circuit, see how many people have died on the Annapurna Circuit.

Accommodation and Food: The Honest Version

Set expectations correctly and you will love this trek; set them wrong and the first night in Meta will surprise you. Inside the Nar Phu valley, teahouses are basic: simple twin rooms, shared squat toilets, no showers in some villages, and dining rooms warmed by a single stove. This is not a defect; it is the deal. The valley's isolation is precisely what preserved the culture you came to see. Facilities improve sharply once you rejoin the circuit at Ngawal, and Manang feels like a resort by comparison.

Food inside the valley is simple and local: dal bhat above all; thukpa and Tibetan bread; potatoes grown in the villages; and yak in several forms, dried, curried, and in momos, which is a genuine specialty of the region. Vegetarian eating is easy and, above 4,000 meters, wise. On the two lodge-less walking days (Koto to Meta, Phu to Nar), we carry packed lunches. Drink three to four liters a day, use the purification tablets we provide, and skip alcohol until you are over both passes. Menus widen again from Manang onward; the full trail food picture is in food and drinks on the Annapurna Circuit.

One night deserves special mention: many Nar Phu itineraries, including ours when conditions align, offer the chance to sleep at the Nar Phedi monastery, where the nuns host trekkers and dinner is cooked in the monastery kitchen. It is regularly the night people remember most.

Connectivity: Expect to Disconnect

Treat the restricted valley as offline. Mobile signal (NTC and Ncell) is patchy to absent from Meta through Nar; WiFi is rare and unreliable; and electricity for charging is limited, solar in places, and paid. Signals and services return at Ngawal and improve through Manang. Download offline maps before Koto, carry a power bank, buy a local SIM in Kathmandu for the sections that do connect, and tell people at home to expect silence for four to five days. Full details in the WiFi, network, and electricity guide.

Distance and Route

From the trailhead at Dharapani to Muktinath, the walking route covers roughly 110 to 120 kilometers (68 to 75 miles) across twelve trekking days, detouring off the classic line at Koto, through the Nar Phu valley, over Kang La to Ngawal, and rejoining the circuit to Thorong La. The route map and elevation chart on this page show the full profile: two great climbs to above 5,300 meters with the deep valley of Manang between them.

Culture of the Nar Phu Valley

The valley's people are of Tibetan origin, and their world is organized around Buddhism in a way few accessible places still are. Phu's monasteries include the historic Tashi Lhakhang Gompa; Nar keeps four gompas around its barley fields; chortens and mani walls mark every approach, and prayer flags run the ridgelines. Walk clockwise around all religious monuments, ask before photographing people or inside gompas, dress modestly in the villages, and accept butter tea when offered; small courtesies open real doors here. Yak herding, barley farming, and wool work remain the economy, and the trade route to Tibet shaped everything from the architecture to the dialects, which are closer to Tibetan than to Nepali. This cultural intactness is the true luxury of the trek, and it exists because the permit system keeps numbers low.

Alternatives and Related Treks

If Nar Phu appeals but this exact route does not fit, four doors are worth opening. The standalone Nar Phu Valley Trekking route visits the restricted valley without continuing over Thorong La, a shorter commitment with the same cultural core. The Annapurna Circuit with Tilicho Lake Trek swaps the restricted valley for the highest great lake of the region for USD 1,085. The Manaslu with Annapurna Circuit Trek is the bigger sibling, joining two circuits and two restricted-area cultures in three weeks. And the Classic Annapurna Circuit Trek remains the benchmark walk without restricted permits. For deciding between regions, the comparison of Manaslu versus the Annapurna Circuit covers which wilderness suits which trekker.

Packing List Essentials

The full Nepal packing system applies, with three Nar Phu specifics on top: warmth for village nights that drop far below freezing, self-sufficiency for the lodge-less days, and pass-day gear for two crossings. The core: layered clothing from wicking base layers to a serious down jacket; a waterproof shell; broken-in ankle-support boots; liner plus insulated gloves; a warm hat, sun hat, buff, and category 3 or 4 sunglasses; trekking poles; a headlamp with spares; two liters of water capacity; personal first aid and medications; and NPR 25,000 to 30,000 in cash. We provide the big-ticket items free: a minus-15-rated sleeping bag and down jacket, crampons when conditions require them, purification tablets, and a duffel. The complete item-by-item checklist is in the Annapurna Circuit packing list.
