The Colorado River, or the Rio Colorado (Spanish pronunciation: [ˈri.o koloˈɾaðo]), in Costa Rica is a tributary of the San Juan River which flows 96 km towards the Caribbean in the northern parts of Heredia and Limón Provinces. The surrounding habitats are protected as part of the second largest rain forest preserve in the country, the Barra del Colorado Wildlife Refuge.
The river is a well known tourist destination, particularly for fishing for tarpon and snook.
