Chacaltaya is a mountain in the Cordillera Real of Bolivia, reaching a height of 5,421 meters. For decades, it was famous for being the site of the world's highest ski resort, accessible to residents of nearby La Paz. The mountain was formerly capped by the Chacaltaya Glacier, which was estimated to be 18,000 years old. However, due to climate change, the glacier rapidly receded and completely disappeared by 2009, making it a stark global example of environmental degradation. Today, the mountain remains an important scientific hub, hosting the Mount Chacaltaya Observatory, where researchers study cosmic rays and atmospheric physics due to the high elevation and clear skies. It is still a popular day-trip destination for tourists, as a road leads nearly to the summit, providing one of the easiest ways to experience altitudes over 5,000 meters and enjoy views of the Altiplano and neighboring peaks.

📋 Practical info
Getting there
Chacaltaya is highly accessible from La Paz, typically reached via an organized half-day bus or 4x4 tour. The narrow, winding mountain road takes visitors directly to the former ski lodge at a very high altitude.
Best season
The site is reachable throughout the year, but the dry season spanning from May to October is preferable, as the dirt road is less muddy and the sweeping views of the surrounding Cordillera Real are clearer.
Terrain & paths
The terrain consists of a rocky, barren high-altitude plateau with patches of snow. The short walk from the lodge to the summit follows a marked but rocky trail on a fairly steep incline.
What to bring
Warm, windproof clothing is absolutely crucial, even on sunny days, as the thin air provides little insulation. Good walking shoes and high-SPF sunscreen are also necessary for the brief hike.
Parking
There is a parking area directly next to the abandoned ski lodge at the end of the road, where tour buses and private transport wait while visitors complete the final ascent on foot.
Safety
The primary danger is the extreme altitude of over 5,300 meters, which can cause severe headaches and shortness of breath; moving slowly and staying hydrated is imperative to avoid altitude sickness.
Time needed
The drive from La Paz takes roughly two hours each way. The actual visit at the lodge and the hike to the summit typically lasts between 1 and 2 hours, making for a standard half-day trip.
