SCHOONER CRUISE – ILHA ANCHIETA, the former prison island. Ilha Anchieta is one of Ubatuba's main attractions, reached by schooner, speedboat and other vessels. It has seven beautiful beaches plus Atlantic Forest protected by the Ilha Anchieta State Park, with trails for taking in the scenery and a remarkable historical tour: the ruins of the old prison, shut down after an uprising decades ago. The island is stunning thanks to the conservation work behind it. Its clear waters draw divers, and its calm beaches and untouched nature are a sight to behold.
