About this site
Dois Rios sits on the southern shore of Ilha Grande, an island off the coast of Angra dos Reis in Rio de Janeiro state, along Brazil's Costa Verde. The area is known for the former penal colony that once stood there, and the surrounding waters are dotted with rocky points and small bays typical of this stretch of coast. The dive site here is rated advanced, so divers should be prepared for more demanding conditions than the calmer bays elsewhere around the island.
