The Rincón de la Vieja Volcano, located in the northwestern part of the country in the Guanacaste province, is one of the most active volcanoes in Costa Rica. It stands out for its various volcanic activities: fumaroles, mud pools, hot springs, solfataras, geysers, and more. Some of these are used for geothermal energy production.
The park covers over 14,000 hectares and is divided into two sectors: Las Pailas and Santa María. The first leads to mud basins, while the second takes you to waterfalls.
It’s possible to explore the park on horseback or by foot. Often overlooked, Rincón de la Vieja National Park is a beautiful place for hiking, with trails spanning around 10 kilometers.
The Rincón de la Vieja Volcano and its national park are part of the Guanacaste Conservation Area (ACG), managed by SINAC, and were declared a World Heritage Site in 1999. Established in October 1973, Rincón de la Vieja National Park is the most visited park within the ACG.
