Caño Island Biological Reserve
Located about an hour’s boat ride from Dominical, this uninhabited island is known as an excellent diving spot – rated as being one of the best underwater diving spots in the world. Trails on the island lead to a pre-Columbian cemetery and several of Costa Rica’s mysterious stone spheres. Mystery shrouds the history of these hand carved and perfectly rounded spheres, which measure from one to two and a half meters in diameter and are found mainly in the Palmar region and on Caño Island.
