Annapurna I: height, first ascent and the Sanctuary

3 min readUpdated 23 Oct 2026By the Base Camp Hikes trek team

Annapurna I is 8,091 m high and is the tenth highest mountain in the world. It was the first 8,000 m peak ever climbed, by a French expedition in June 1950. It has a serious reputation among climbers, and trekkers can see it from the Annapurna Sanctuary.

Height and the range

Annapurna I is the highest peak of the Annapurna Himal, a long range with many peaks above 7,000 m, including Annapurna South, Hiunchuli, Gangapurna and Machhapuchhre. The name is Sanskrit and is usually translated as goddess of the harvests.

First ascent

Maurice Herzog and Louis Lachenal of France reached the summit on 3 June 1950. It was a famous expedition, and the descent was dramatic and severe. The climbers suffered badly from frostbite, and the story became a classic of mountaineering writing.

Climbing reputation

Annapurna I is considered one of the most dangerous eight-thousanders because of avalanches and steep terrain. Few climbers attempt it each year, compared with Everest.

The Sanctuary and base camp

Trekkers do not climb Annapurna I. They walk into the Annapurna Sanctuary, a high basin ringed by peaks, to Annapurna Base Camp at about 4,130 m. The view from there is of a wall of mountains at close range. See the Annapurna Base Camp guides.

How long and how hard

The trek takes about seven to twelve days, depending on the start point. Altitude is moderate, though cold at the top. See the days and itinerary.

Other views of Annapurna

The Annapurna Circuit, Poon Hill and Mardi Himal treks also show the range. See Annapurna Base Camp versus the Circuit.

Annapurna names and peaks

The Annapurna Conservation Area covers a vast region, and many peaks have local and foreign names. Annapurna South, Annapurna II, III and IV, Gangapurna and Machhapuchhre all stand near the Sanctuary.

Safety on the trek

Avalanches affect the upper Sanctuary in late winter and spring after heavy snow. Guides watch conditions and may change the plan. Follow their advice and keep to marked trails.

Common questions

Is Annapurna I climbable by trekkers? No, only by expedition climbers. Is the base camp view worth it? Most trekkers say yes. How cold is it? Nights at the base camp are below freezing, even in the main seasons.
