The ACA encompasses the Thorong La Pass, one of the highest navigable mountain passes in the world at 5,416 meters.
It is home to the Muktinath Temple, a sacred site revered by both Hindus and Buddhists, known for its natural gas-fueled eternal flame.
The region is a crucial habitat for the elusive snow leopard, with populations monitored through ongoing conservation programs.
The Tilicho Lake, located within the area, is one of the highest altitude lakes on Earth at approximately 4,919 meters.
The area incorporates the ethnic heartlands of the Gurung, Thakali, and Manange communities, each with distinct cultural traditions.
The Kali Gandaki River, which carves the deepest gorge, predates the rise of the Himalayas, maintaining its course as the mountains were uplifted.
The region contains a unique blend of semi-arid trans-Himalayan desert, particularly north of Jomsom, which shares more climatic similarities with Tibet than the rest of Nepal.
The Annapurna Conservation Area (ACA) is Nepal's largest protected area, covering 7,629 square kilometers of the Annapurna range. It spans elevations from 790 meters to the 8,091-meter summit of Annapurna I. The region features the world’s deepest gorge, the Kali Gandaki, which separates the Dhaulagiri and Annapurna massifs. Visitors encounter a massive gradient of ecosystems, ranging from subtropical forests to alpine meadows and trans-Himalayan desert landscapes. The area operates as a community-managed conservation site rather than a restricted national park, allowing indigenous populations to live within its boundaries. Key hiking circuits include the Annapurna Circuit and the trek to Annapurna Base Camp. The geography is characterized by high-altitude arid zones in Mustang and humid, densely forested slopes in the south. Biodiversity includes over 1,200 species of plants, 100 mammal species, and 478 bird species. Access to the area is regulated through the mandatory ACAP entry permit system.
