Cano Island is part of a mountain, or what s left of one. Like some dystopian biblical future, the island s 740 acres are the peak of an underwater mountain formed during the violent collision of tectonic plates along Costa Rica s coast line. Wild cocoa, rubber, strangler figs and trumpet trees grow inside the island, rimmed by sandy white shores. Within the forest, hide the remains of its Pre-Columbian inhabitants, the Diquis tribe. Several mysterious granite spheres mark the island suggesting that Cano Island was previously used as an ancient burial ground.
