Rincón de la Vieja Volcano National Park
Home to some of the most startling and unique scenery in Costa Rica, Rincón de la Vieja National Park and its eponymous volcano welcomes visitors to volcanic landscapes, complete with steaming fumaroles, boiling mud cauldrons, and natural hot springs.
A literal hotbed of outdoor activity, the park is best known for its hiking trails, which range from easy to high difficulty. During the wet season, Rincón de la Vieja Volcano National Park turns green and lush, and the park’s waterfalls roar with activity.
