Huayna Potosí (6,088 m) is the glaciated peak of the Cordillera Real about 25 km north of La Paz, and the 6,000 m mountain most often climbed by people new to glacier travel. The normal route goes from the Zongo refugios (about 4,700 m) to Campo Alto Roca at 5,130 m, then up the glacier on a night start to the top: about 960 m of climbing on the final day, usually 5 to 6 hours up, and back to La Paz the same afternoon. It is not a trek. You walk roped on a crevassed glacier with crampons and an ice axe, and a steeper step around 5,600 m may need rope work.

The three-day programme
Day 1: Zongo and glacier practice
Transport from La Paz to the refugios below the Zongo pass takes 1 h 30 min to 2 hours; daily buses also leave Plaza Ballivián in El Alto early in the morning. The afternoon is spent on the glacier toe practising crampon technique, ice-axe arrest and moving roped together. Sleep at about 4,700 m.
Day 2: up to Campo Alto Roca
A 2 to 3 hour climb on rock and scree brings you to Campo Alto Roca, the stone refuge also called the Casa de Guías, at 5,130 m. Dinner is early and sleep is short; this is the night most people feel the altitude.
Day 3: the glacier to 6,088 m
Teams leave around 1 am to climb while the snow is frozen. The route crosses open glacier with crevasses, then a steeper section near 5,600 m that may need rope work, before the final ridge. Five to six hours up, two to three down to high camp, then down to the road and back to La Paz.
Is Huayna Potosí for you?
Honest test: if you have trekked above 4,500 m without trouble, can walk uphill for six hours on little sleep, and are willing to turn round when your guide says so, it is a realistic first 6,000 m peak. If you have never been above 4,000 m, spend your first days in La Paz (3,640 m) and do lower acclimatisation walks before the climb. The CDC advises not raising your sleeping altitude by more than about 500 m a day above 2,750 m; CDC guidance on high altitude and our altitude sickness guide explain the warning signs.
Guides, gear and fees
No law requires a guide on Huayna Potosí, and some climbers organise it themselves. Without solid glacier and crevasse-rescue skills, go with a guide: the danger is the glacier, not the walking. Agencies in La Paz rent boots, crampons, harness, helmet and ice axe. The mountain is not inside a national park, so there is no park entrance fee; expect a small police-checkpoint charge on the road and a per-person charge for the refugios. Ask your agency what its price includes.
Safety notes
- Crevasses: always rope up on the glacier, even on a well-trodden track.
- Cold: the final day starts well below freezing; mitts and a down jacket are standard.
- Health: check the CDC Bolivia page for vaccination advice before you travel.
- Turnaround time: agree it before you leave high camp and keep to it.
- Road blockades are common in Bolivia and can cut overland routes without warning; the US Embassy in La Paz warned on 9 September 2026 that blockades were expected to resume, and the previous round disrupted overland travel for more than seven weeks. Check local news and embassy alerts the day before you drive to a trailhead.
