Parque Nacional Sajama, located in the Bolivian Andes, is renowned for its stunning high-altitude landscapes, including the towering Nevado Sajama volcano, hot springs, and unique Andean wildlife such as vicuñas and flamingos. Due to the altitude and remote location, accessibility can be challenging, with rough roads and limited infrastructure, making guided tours highly recommended, especially for acclimatization and navigating the park. Solo visits are possible for experienced high-altitude trekkers. The dry season (May-September) is the best time to visit, avoiding the rainy season which can make roads impassable. Costs can vary significantly depending on the tour operator and services chosen, but expect to budget for transportation, accommodation, park entrance fees, and potentially oxygen support. A typical visit duration ranges from 2 to 4 days to fully experience the park's highlights and acclimatize to the altitude, with hiking and soaking in hot springs being popular activities.
