Both Ancohuma and Illampu are located in the northern Cordillera Real, they dominate the east coast of Lake Titicaca (especially from Isla del Sol)

Ancohuma was first climbed by two Germans mountaineers - Adolph Schulze and Rudolf Dienst on June 11th 1919 from Cocoyo via Laguna Negra. The two climbers needed 6 days to reach the summit.

Miscellaneous Info


  • It is nearly impossible to buy white gas for the stoves in La Paz. Butane/Propane canisters are available at trekking agencies in La Paz.

  • Basic food is available at the market in Sorata. Bring the food for the high camps from La Paz.

  • Several cartographers (also the Times World Atlas) have claimed that Ancohuma is the highest mountain in Bolivia; and have stated the height up to more than 7000m, which would be the highest and only mountain over 7000m outside the Himalayas. The actual edition of the DAV Map (Cordillera Real - Nord, Illampu) states Ancohuma's altitude 6427m.

We did not find any white gas in La Paz. We heard that one trekking agency in La Paz sells white gas (but too late for us)

Bring a multifuel stove. Kerosene and white gas (bencina blanca) can normally be found in the auto workshops and painting shops.

The elevation controversy has been put to rest. In 2002, OWA of Colorado guided a group of teenagers, to the summit and confirmed the actual height of Ancohuma to be 6425 m +/- 2m. The project was sponsored by Trimble and OmniStar and overseen by Jerry Brown of Bear Creek Surveying in Durango who has now mapped the Colorado Trail 3 times and rediscovered the lost Silver Trail in Copper Canyon, Mexico. Here's the link to the full story --
