Ilha Grande

Geologically speaking, Ilha Grande is located in the oriental terrain of the northern Ribeira belt. The core of the island is formed by Precambrian granites with peaks above 1.000 m. Posterior to the collisions of the Neoproterozoic Brasiliano cycle, they intruded the surrounding, softer charnokite rocks.
These igneous intrusive rocks (also called plutons) cooled and crystallized deep below the Earth's surface (10 - 20 km). Erosion and tectonics, during the last 500 million years, brought them up to the Earth's surface and made them visible to us. They are nowadays covered by dense submontane and montane tropical rainforest.
Some ruins, partly covered by the lush vegetation of the Atlantic rainforest, remember Ilha Grande's dark history as a shelter for pirates, a center for contraband slave trade, a quarantine hospital and a high securitiy penitentiary. During the last years, Ilha Grande with its 106 beaches, 14 bays, 4 lakes, 10 rivers and 3 grottos, has become one of the most visited ecotourism locations in the state of Rio de Janeiro. Several rainforest trails take the hiker to the most isolated places of the island – Travel to Brazil / Tours.
