Ilha Grande is an island located off the coast of Rio de Janeiro state, Brazil. The island, which is part of the municipality of Angra dos Reis, remains largely undeveloped. For almost a century it was closed by the Brazilian government to free movement or settlement because it first housed a leper colony and later a top-security prison. The Cândido Mendes prison, which housed some of the most dangerous prisoners within the Brazilian penal system, was finally closed in 1994. The largest village on the island is called Vila do Abraão with approximately 1900 inhabitants.
The island, which is 193 km2 in area, is now a popular tourist destination that is noted for its scenic beauty, unspoiled tropical beaches, luxuriant vegetation and rugged landscape. The highest point is the 1,031 m Pico da Pedra D'Água. Most of its territory is within the Ilha Grande State Park. The remainder of the island is subject to stringent development restrictions.
