Annapurna Conservation Area (ACAP)

ACAP is one of the first conservation projects undertaken in Nepal to conserve, protect and decentralize the nature conservation attempts. It spans over 5 different districts and covers the entire Annapurna massif. It is also the largest conservation areas available in Nepal.


Annapurna Conservation Area or ACAP is located at the mid-western region of Nepal. It covers 7,629 and spans over 5 different districts, namely; Manang, Mustang, Kaski, Myagdi and Lamjung. The ACAP HQ is located at Ghorepani village, one of the most visited tourist places in Nepal.


The area has two distinctive climatic regions within a span of 120 km. The southern hills of ACAP region receive frequent rainfall, whereas, the northern most parts receive no or less rainfall, hence, the latter are known as rain-shadow areas.

The deepest gorge in the world – Kali Gandaki, and Annapurna I – Eight-Thousander, is located inside the ACAP.

Gurung and Magar are the predominant ethnic tribes in the lower ACAP regions, whereas Thakali, Manange and Loba are mostly found in the higher regions.

Tourism is undoubtedly one of the major benefactor of the ACAP project. The proceeds received from the permits are used for the local conservation programs.

Wildlife & Flora

ACAP is rich in biodiversity and is a haven for the 1,226 species of flowering plants, 102 mammals, 474 birds, 39 reptiles and 22 amphibians.


ACAP was launched in 1986 with the initiation of King Mahendra Trust for Nature Conservation (KMTNC) to protect the environment with sustainable community development in Annapurna area by the local people without any intervention from the Nepalese Government and/or any other institutions.

It was gazetted in 1992 and is managed by the National Trust for Nature Conservation. The main motto of the project is to conserve the resources, tourism management, community development, education and extension.

ACAP with the participation of the trekkers have been able to increase the standard of living of the local population, protect the environment and develop sustainable tourism.


A trekker is required to obtain an ACAP permit before entering the region.

The ACAP covers;

  1. Annapurna Base Camp
  2. Ghorepani-Poon Hill
  3. Lower/Upper Mustang
  4. Annapurna circuit
  5. Sikles trail

Hence, anyone doing these treks must obtain the ACAP permits. The region receives more than 100,000 trekkers in a year, mainly due to the popularity of the base camp and circuit trails.

Tilicho Lake is located in the Manang district of Nepal, at around 55 km from Pokhara. It is situated at an altitude of 4,919 metres (16,138 ft) in the Annapurna range.

Due to its sheer altitude, it’s known as the highest lake in the world. The max length of the lake is 4 km, with the width of 1.2 km. The average depth is 85 meters.

Khangsar, Tilicho, Muktinath and Nilgiri are few of the peaks surrounding the lake.

Tilicho Lake was the site of one of the highest ever altitude scuba dives. A Russian diving team, consisting of Andrei Andryushin, Denis Bakin, and Maxim Gresko, conducted a scuba dive in the lake in 2000.


The lake is a part of the popular trek trails in the mid-western Nepal. You can consider visiting the lake by going offbeat from the Annapurna circuit or consider doing a trek straight to Manang during the Manang-Tilicho Trek.

It may take 5-8 days from Besi Sahar to reach the Tilicho Lake. The trail offers enough the-houses or lodges, hence camping isn’t required. The periphery of the lake doesn’t have any lodges, hence, you must consider staying at Tilicho Base Camp and only doing a day tour of the lake.
