The Corcovado National Park lies in the South Pacific region of Costa Rica, on the Osa Peninsula. It is the largest of the parks as it encompasses one third of the Osa Peninsula.
A huge biodiversity can be found here. It is believed to have the highest concentration of macaws and virgin lowland rainforest in Central America, contains 10% of the mammels found in the Americas and gives home to 500 different species of trees, 6000 species of insects, 400 species of birds and 40 species of fish.
Since camping is permitted, 2-3 day tours are very common. From Puerto Jiménez the park can be accessed by driving 44km (27 miles) south along Highway 245.
