The Osa Peninsula is located on the Pacific coast, in the southwestern part of the country and it is the second largest peninsula of Costa Rica. Corcovado National Park is home to the largest population of scarlet macaws and the best tropical rainforest on the Pacific coast of Central America. Its extensive biodiversity includes more than 400 species of birds (20 of which are endemic), 139 mammals and 116 reptiles and amphibians.
On the opposite side is Golfito, which was once the most important port in the southern end of Costa Rica; today it is a wildlife refuge. Since the 1990s, the free zone and the newly developed ecotourism industry have been reviving the region because of the tourists visiting the protected areas and the nearby botanical gardens and the boat excursions on the pristine waters of Golfo Dulce and the Coto River.
