Dive-site story
Situated within the protected waters of Caño Island Biological Reserve off the Osa Peninsula, this dive centers around a volcanic cavern carved into the reef. Divers hover outside the wide entrance to watch whitetip reef sharks resting on the sand floor inside. Surrounding volcanic boulders and rocky ridges host dense aggregations of pelagic fish and patrolling stingrays, while surge gently pushes through the channels.
