Sirena Station
The heart of Corcovado National Park, where rainforest, rivers, and Pacific coastline meet at one of the best wildlife-watching sites in Costa Rica.
History
About the station
Sirena Station is the central ranger and research station of Corcovado National Park, set on the lowlands where the Sirena and Pavo rivers meet the Pacific Ocean. For decades it has served as a base for park rangers, biologists, and researchers studying one of the last great expanses of Pacific lowland rainforest in Central America.
Today Sirena remains the park's main hub, connected by trail to the La Leona and Los Patos entrance stations. ADI Corcovado manages the station's lodging and food service, supporting the visitors, volunteers, and researchers who pass through.
