The Annapurna Circuit is the trek that made Nepal’s teahouse trekking famous: a long, shape-shifting loop that carries you from subtropical river valleys, through pine forest and apple orchards, into high Himalayan desert and over a 5,416-metre pass. Road-building has changed it, but with the right planning it remains one of the great walks in the world — and one that a reasonably fit first-timer can complete.
Permits you need
Two documents, both easy to arrange in Kathmandu or Pokhara:
Trekking in Nepal? Get properly insured.
Most standard policies don’t cover high-altitude trekking or helicopter evacuation. Choose cover that does before you leave for the mountains.

- ACAP — the Annapurna Conservation Area Permit.
- TIMS card — the Trekkers’ Information Management System card.
Bring passport photos and your passport. Rules on solo trekking and guide requirements have tightened in recent years, so check the current position before assuming you can walk unaccompanied.
Permit costs and guide rules change; verify the latest with the Nepal Tourism Board or a registered agency.
How long it takes
A traditional full circuit runs roughly 12 to 18 days depending on where you start and stop and how many side trips and acclimatisation days you build in. Because a road now reaches deep into both the Marsyangdi and Kali Gandaki valleys, many trekkers shorten the walking by taking a jeep past the lower, dustier sections and starting higher — a legitimate choice that trades some scenery for less road-walking.
The pass, and the real risk
The crux is Thorong La. Fitness is rarely what ends an attempt — altitude is. The single most important thing you can do is ascend slowly and build in acclimatisation days, particularly around Manang before the pass. Learn the early signs of altitude sickness (headache, nausea, poor sleep, breathlessness at rest) and treat “going down” as always available and never a failure.
A rough shape of the route
| Stage | Character | Note |
|---|---|---|
| Lower valleys | Subtropical, villages, road sections | Many now jeep past part of this |
| Manang area | Alpine, acclimatisation base | Build in rest/altitude days here |
| Thorong La (5,416m) | The high pass | Early start; weather-dependent |
| Muktinath & down | Pilgrimage site, then Kali Gandaki | Descent into Mustang district |
What to pack
Layers matter more than any single heavy item. On the same day you can face sub-zero wind near the pass and warm sun in the valleys. Non-negotiables: broken-in boots, a warm insulated layer, a windproof shell, sun protection (the high-altitude sun is fierce), a reusable water bottle with a purification method, and cash — ATMs are scarce once you leave the trailhead towns.
Best time to go
October–November and March–April are the classic windows: stable weather, clear mountain views and open teahouses. Winter is possible but cold and the pass can close with snow; the summer monsoon brings cloud, leeches at lower elevations and landslide risk on the roads.
