Diria National Park preserves the tropical and higher elevated cloud forests of the central highlands of the Nicoya Peninsula. It spans over app. 13,500 acres in the Guanacaste Province. Rivers that form basins with app. 2,500 ft (app. 800 mt) in altitude change. With scenic hiking-trails and a basic cabin this might be a nice group or biological research and exploration destination.
Getting there is via Liberia from the North towards Santa Cruz. The entrance to Diria National Park is about 10 km south of Santa Cruz heading towards Nicoya. From the South take the Tempisque Bridge turn right towards Nicoya and Santa Cruz.
