Preciosa Platanares Wildlife Refuge Costa Rica was created on April 20th 1998, to protect forested and beach areas on the Osa Peninsula in the Pacific Coast of Costa Rica.
The Platanares Preciosa Wildlife Refuge is a protected coastal-marine area, belonging to the Osa Conservation Area (ACOSA), which is a very important center 
for the conservation of wildlife and natural resources of a very particular ecosystem. This refuge is also a biological corridor between Corcovado National Park and Golfo Dulce reserve.
The Preciosa Platanares National Wildlife Refuge mangroves are both relaxing and amazing. The mangroves are intense environments where wildlife shows in many different ways. You will learn about the ecosystem while sailing in calm waters, and at the same time, visitors can enjoy watching dolphins, sea turtles, fish, crabs, crocodiles, caimans, ocean birds and coatis, anteaters, raccoons, monkeys, iguanas, Jesus Christ lizards, snakes and butterflies hiding in the forest.
The refuge has the same climate that prevails in the Osa Peninsula, very humid with heavy rains, evergreen forests and an average temperature of 25ºC (70ºF), so the Preciosa and Platanares beaches have a unique vegetation with a variety of “Piñuelas” or “Piros” (Bromelia plumieri).
Immerse yourself in indescribable wild and silent beauty, where nature reveals its life. This trip explores the mangrove estuaries near the Platanares River in the Preciosa Platanares National Wildlife Refuge.
There are no public facilities at Preciosa Platanares National Wildlife Refuge. Other nearby Costa Rican Parks include Golfo Dulce Forest Reserve, Hacienda Copano Wildlife Refuge, Carate Wildlife Refuge, Lagunazul National Wildlife Refuge, Rio Oro National Wildlife Refuge and Corcovado National Park.
