Climbing Sajama in Bolivia, At 6,542 meters (21,463 ft), Nevado Sajama is the highest mountain in Bolivia and the majestic crown of the Cordillera Occidental.
Sajama is an extinct volcanic peak located in the Oruro Department, approximately 200 km southwest of La Paz and close to the Chilean border. For experienced mountaineers seeking a true high-altitude adventure, climbing Sajama offers one of the most rewarding and challenging ascents in the Andes.
Why Climb Sajama?
Nevado Sajama is an excellent choice for climbers looking for a thrilling expedition. The climb is physically demanding due to its extreme altitude, freezing temperatures, dry air, and often strong winds. The route also includes steep sections that add to the challenge.
The effort is rewarded with spectacular scenery throughout the ascent and breathtaking panoramic views from the summit. On clear days, climbers can admire the famous Payachatas Volcanoes—Parinacota (6,342 m) and Pomerape (6,282 m)—along with countless snow-capped peaks stretching across Bolivia and Chile.
Sajama National Park
Sajama National Park is one of Bolivia’s most remarkable protected areas. It is renowned for its unique high-altitude desert landscape, rich wildlife, and volcanic scenery.
The park is home to llamas, alpacas, vicuñas, Andean foxes, and flocks of pink flamingos. It also protects beautiful forests of queñua trees, the world’s highest-growing forests. Visitors can enjoy impressive geothermal features, including natural hot springs and geysers, making the area an exceptional destination even beyond the climb itself.
Physical Requirements
Climbing Nevado Sajama requires excellent physical fitness and proper acclimatization. The combination of high altitude, low oxygen levels, cold temperatures, strong winds, and dry volcanic air makes this a demanding expedition.
To maximize your chances of reaching the summit safely and comfortably, climbers should arrive well acclimatized and have previous experience hiking or climbing at high altitude. Good cardiovascular fitness and endurance are essential.
Where Do Sajama Expeditions Start?
Most climbing expeditions begin in La Paz, Bolivia.
La Paz is easily accessible by international and domestic flights and is one of the world’s highest capital cities, making it an ideal place to begin acclimatization. Many climbers also spend several days climbing peaks in the Cordillera Real before attempting Sajama.
The Normal Climbing Route
The standard route follows a gradual progression over several days:
- Day 1: Drive approximately 4 hours from La Paz to the village of Sajama, then hike about 3 hours to Base Camp (4,700 m).
- Day 2: Hike about 5-6 hours to high Camp (5,700 m).
- Day 3: Summit attempt (6,500 m). The climb to the summit and return to High Camp typically takes around 10 hours. After a short rest at high camp, descend to Base Camp or continue to the village.
- Day 4: From Sajama Village we retun to La Paz City.
Weather Conditions
Due to its extreme altitude, Nevado Sajama remains cold throughout the year. Temperatures frequently drop well below 0°C (32°F), especially during the night and on summit day. Strong winds are common and can make conditions feel significantly colder.
