Caño Island, off Costa Rica’s Caribbean coast, offers a genuine feel of big animal action. We’ve seen everything from schooling fish thick enough to make you feel like you’re swimming through a cloud, to the distinct silhouettes of hammerhead sharks cruising by. Whale sharks and mantas sometimes make an appearance, particularly in season, alongside plenty of dolphins and turtles. It’s a site that suits both newer divers looking for a thrill and more experienced folks who appreciate the pelagic opportunities. Definitely a worthwhile trip for those who like their diving with a side of the dramatic.
