Not only do the waters surrounding Caņo Island contain some of the most abundant and varied marine life in the world (see Diving), but the island also possesses several pre-Colombian archeological artifacts. These artifacts can be explored on several hikes through the lush tropical vegetation. The perfectly spherical stones are believed to have once marked an offshore burial ground and ceremonial site for the indigenousDiquis tribe who inhabited the Golfo Dulce area until the arrival of the Spanish. Along with the stone spheres, Caņo Island is believed to have once been a pirate hideout and some go so far as to claim that the island was the inspiration for Robert Stevenson's Treasure Island.Furthermore, within 50 feet (15 meters) of the beach you can explore the warm crystalblue waters with a mask, fins and snorkel and see the wide variety of brilliantly colored tropical fish and coral species that call Caņo Island home.

The Jinetes de Osa offers guided hikes of Caņo Island that include lunch and snorkeling gear if you desire.
