The Cordillera Real is the great snowy wall that rises east of La Paz, Bolivia, a compact chain of glaciated 6,000-metre peaks that includes Huayna Potosí at 6,088 metres and the triple-summited Illimani at 6,438 metres. No other capital city in the world sits beneath such a dramatic mountain backdrop. The range draws both trekkers, who walk high circuits between turquoise lakes, and climbers, for whom Huayna Potosí is one of the most accessible 6,000-metre summits in the Andes.
Why go
The Cordillera Real concentrates the Andes at their most spectacular into a single accessible range. Trekking routes like the Condoriri circuit link remote valleys, high passes and glacial tarns over several days, with condors and vicuñas for company. For climbers, the range offers everything from straightforward glacier ascents to serious technical faces. The cultural layer is rich too: Aymara villages, mining settlements and the living traditions of the high Andes surround the peaks.
Best time to visit
The dry season, roughly May to October, is generally the climbing and trekking season, with clearer skies and more stable conditions. Nights are bitterly cold at altitude during these months, and the sun is fierce by day. The wet season from November to March brings snow, cloud and avalanche risk on the high peaks. June through August is the busiest window for guided ascents of Huayna Potosí.
Getting around
La Paz is the base for the whole range. Trailheads and climbing approaches are reached by road, usually with a 4×4 or an arranged transfer, from the city or from villages like Tuni and Zongo. Most climbs are done with local guides and organised logistics; independent trekking is possible on some routes but requires solid mountain experience. Confirm current access and guide requirements locally before you plan, as arrangements vary by peak and season.
Good to know
- Acclimatisation is everything. Spend several days in La Paz before attempting anything above 5,000 metres, and ascend gradually.
- Nights above 4,500 metres are extremely cold. Bring a proper four-season sleeping bag and full winter clothing even in the dry season.
- Glacier travel on the 6,000-metre peaks requires ropes, crampons and crevasse-rescue knowledge. Go with a qualified guide unless you have these skills.
- The sun at tropical latitudes is brutal. Protect your eyes and skin even on overcast days.
- Carry cash in bolivianos for mountain villages. ATMs and card acceptance are essentially nonexistent beyond La Paz.
The Cordillera Real is the Andes in concentrated form: huge peaks, high culture and thin air, all within sight of La Paz. Acclimatise properly and the range will reward you.
