Area de Conservacion Guanacaste

Within Guanacaste, visitors can explore several Costa Rica volcanoes, the most notable being the Rincon de la Vieja, which has three craters and one lagoon. It last erupted in 1970, but fumarole activity still occurs in one of the craters.

In addition to the volcanos, the marine land here is just as impressive, including various near shore islands and islets, 37 wetlands, and miles of sea turtle nesting beaches. The wetland forests are considered to be among the most pristine in the world.

During the nesting season, along the Naranjo and Nancite beaches, thousands of turtles come to shore to nest. These species include leatherback, hawksbill, and olive ridley turtles - the most prominent in this area.

Vegetation in the area includes fig and rosewood trees, evergreen gallery forests along streams, savannahs, oak forests, and mangroves.  Wildlife within the Area de Conservacion Guanacaste includes white tailed deer, white lipped peccary, collared peccary, tapir, white faced monkeys, spider monkeys, howler monkeys, collared anteaters, jaguars, margays and ocelots. There well over 200 species of birds within the park. The most common are the rufescent tinamu, spot-bellied bobwhite, great curassow, crested guan, blue-winged teal, roseate spoonbill, thick knee, jabiru, ibis and laughing falcon.
