Nevado Sajama, Bolivia's highest peak and a part of Sajama National Park, offers stunning Andean landscapes and challenging mountaineering opportunities. Accessibility is limited due to its remote location, requiring a 4x4 vehicle. While experienced climbers may attempt solo ascents, hiring a local guide is highly recommended for safety and logistical support, especially given the high altitude and unpredictable weather. The best time to visit is during the dry season, from May to September. Costs vary depending on the chosen activities and level of support, but expect to spend a significant amount on transportation, permits, and guides. A typical visit can range from a few days to a week, depending on whether you're simply exploring the park or attempting to climb the mountain. Be prepared for extreme weather conditions and altitude sickness.
