A four-day, technical ascent of Illimani from La Paz: approach to base camp, glacier high camp at 5,550 m and a pre-dawn summit push to 6,442 m. Ideal for experienced, well-acclimatized mountaineers ready for sustained altitude, steep ice and alpine exposure.

Night in La Paz exits through the window and the silhouette of Illimani grows until it fills the windshield — a hulking, glaciated ridge that seems to dare you to climb. The road climbs for three hours to Pinaya (3,800 m) before donkeys shoulder packs and your boots find the first step toward base camp at 4,600 m. Wind and stone become constant companions as the route tightens into moraine, then glacier, each step higher thinning the air and sharpening concentration.

Reserve your spot on the Illimani - 4-Days today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize first
Spend several days in La Paz or nearby high trails before the trip; acute mountain sickness is the biggest risk on Illimani.
Start early on summit day
Summit bids begin around 1:00 AM to avoid afternoon storms and worsening snow conditions; plan sleep and meals accordingly.
Use crampons and ropes
Steep glacier sections reach ~50°; properly fitted crampons, working harness and rope systems are essential.
Respect weather windows
The Cordillera Real can produce sudden storms—turnaround decisions are mandatory for safety.
Crampons
Provide traction on steep ice and firm snow on the summit ridge.
Mountaineering boots
Stiff, insulated boots for crampon compatibility and multi-day glacier travel.
Technical ice axe & harness
Required for self-arrest, roped travel and protected glacier movement.
Layered insulating jacket (down or synthetic)
Keeps you warm during pre-dawn summit pushes and cold nights at high camp.
