Caribbean Coast Lowlands - Barra del Colorado National Wildlife Refuge Refugio Nacional de Fauna Silvestre Barra del Colorado

This is the biggest national wildlife refuge in Costa Rica covering 92,000ha/227,240ac adjacent to Tortuguero National Park. Combined, the two areas form a large regional conservation area. The northern border of the refuge is the San Juan River, also the border with Nicaragua.

The rainforest and rivers throughout the refuge are home to a number of wildlife, including monkeys, caimans, sloths and several species of birds. While wildlife observation in the refuge is gaining in popularity, the main attraction here is sportfishing.

Barracuda, mackerel, bluegill, rainbow bass and mahaca can be caught in the rivers and offshore, however tarpon and snook are the angler's fish of choice. Deep-sea fishing for marlin and sailfish is also available.
