Rincón de la Vieja National Park is located about 15 miles northeast of Liberia, the capital of Guanacaste Province in Costa Rica. The park encompasses over 34,000 acres and contains two volcanoes and 32 rivers and streams, making it a biodiversity hotspot. The sheer scale of the park allows you to experience both the Caribbean and Pacific sides of the Cordillera de Guanacaste.
