La Amistad International Park
This park is the largest wilderness area in Costa Rica, covering about 194´000 hectares (479´000 acres) of rainforest, cloud forest, alpine tundra (páramo), and glacial lakes in the country. Shared with Panama to the south, the enormous, mostly unexplored park spans a total of 400´929 hectares (990´717 acres),
and has been declared a Natural World Heritage site by UNESCO. It is estimated that two-thirds of all the wildlife in Costa Rica can be found in La Amistad, including pumas, monkeys, coatis, peccaries, giant anteaters, and endangered species like jaguars, ocelots, margays, and tapirs. More than 500 species of birds can be found here, including Harpy Eagles and Resplendent Quetzals.
