Almost every classic trek in central Nepal — Annapurna Base Camp, the Annapurna Circuit, Mardi Himal, Poon Hill, Khopra Ridge, Tilicho Lake — passes through the same protected landscape: the Annapurna Conservation Area (ACA). It's easy to treat this as a formality, a permit you buy and forget about. But ACA is the reason these trails exist in their current form at all.
This guide explains how ACA actually works, from the ground up: what it is, how it's managed, what permits and fees apply today, where the checkpoints are, which treks fall inside its boundaries, and what conservation and cultural rules you're expected to follow.
What Is the Annapurna Conservation Area?
Established in 1986, the Annapurna Conservation Area spans 7,629 square kilometers, making it Nepal's largest protected area. Unlike traditional national parks that exclude human habitation, ACA was designed as a community-managed conservation area. Over 100,000 residents across five districts continue to live, farm, and run teahouses inside its borders.
Why ACA Is NOT a National Park
National parks in Nepal (like Sagarmatha National Park around Everest) are managed directly by government wildlife departments with strict restrictions on land ownership. ACA is governed by the Annapurna Conservation Area Project (ACAP) under the National Trust for Nature Conservation (NTNC), utilizing local conservation committees where tourism revenue stays directly in the local villages.

Annapurna Conservation Area Permit (ACAP) Guide

ACAP vs TIMS vs Mandatory Guide Policy
While ACAP is the entry permit for the conservation area, foreign trekkers are required by Nepal government regulations to trek with a licensed guide. Independent unguided solo trekking on major routes is prohibited. Your agency will typically secure both your ACAP permit and TIMS registration prior to your departure.

Frequently Asked Questions: Annapurna Conservation Area
What is the Annapurna Conservation Area (ACA)?▼
ACA is Nepal's largest protected area, covering 7,629 square kilometers across five districts in central Nepal. Established in 1986 and managed by ACAP under the NTNC, it protects the ecosystems surrounding the Annapurna Massif while allowing local communities to continue living and running tourism businesses inside its boundaries.
Is Annapurna Conservation Area a national park?▼
No. ACA is a conservation area, a distinct legal designation that permits human settlement and community-based management, unlike a national park. You may see 'Annapurna National Park' used online, but that's a common misnomer — the correct designation is Annapurna Conservation Area.
Do I need an ACAP permit to trek in Annapurna?▼
Yes. ACAP is mandatory for every trekker entering the conservation area, regardless of which specific route you're taking. It's checked at multiple checkpoints along the trail.
What is the difference between ACAP and TIMS?▼
ACAP is the conservation area entry permit and is consistently required. TIMS (Trekkers' Information Management System) is a separate trekker registration system whose requirements have shifted over recent years and vary by region, so it's worth confirming current TIMS status directly with ACAP or a licensed operator before you travel.
Where can I get an Annapurna Conservation Area permit?▼
At the ACAP/Nepal Tourism Board offices in Kathmandu or Pokhara, through NTNC's online e-permit system, or arranged on your behalf by a licensed trekking agency.
How much does the ACAP permit cost?▼
NPR 3,000 for foreign nationals and NPR 1,000 for SAARC nationals. Children under 10 are exempt from the fee.
How long is an ACAP permit valid?▼
It's a single-entry permit valid for the full duration of your trek inside the conservation area. Leaving and re-entering ACA generally requires a new permit.
Can foreigners trek Annapurna without a guide?▼
No. Current regulations require a licensed trekking guide for foreign trekkers on Annapurna's major routes — independent, unguided trekking is no longer permitted here.
What wildlife lives inside ACA?▼
Snow leopard, musk deer, and blue sheep are among the notable mammal species, alongside hundreds of recorded bird species including the Himalayan monal. Rare high-altitude wildlife sightings are uncommon on standard routes, since these species avoid trafficked trails.
Which trekking routes are inside the Annapurna Conservation Area?▼
Annapurna Base Camp, the Annapurna Circuit, Mardi Himal, Ghorepani Poon Hill, Khopra Ridge, and Tilicho Lake all fall within ACA's boundaries and require an ACAP permit.
What happens if I trek without a permit?▼
Checkpoints throughout the region check for valid ACAP permits. Trekking without one can result in fines, being turned back at a checkpoint, or being required to return to the nearest permit office before continuing.
When is the best time to visit ACA?▼
Spring (March–May) and autumn (late September–November) offer the clearest views and most stable trekking weather. Winter suits lower-elevation routes, while monsoon season is generally avoided due to rain and obscured views.
