There are few better ways to explore the waters off Varadero than this luxury catamaran cruise. This full day jaunt includes free time and a seafood barbecue on a tropical beach on Cayo Blanco. And to top it off, you'll jump in for a 15-minute encounter with dolphins, too.After setting sail from Varadero Marina, relax aboard en route to your first stop, Rancho Cangrejo – a platform in the middle of the sea. Then, head to tiny Cayo Blanco. This place has a real desert island feel – all powder-like sands, swaying palms and turquoise waters. Drop anchor and hit the beach for a lunch of fresh prawns, lobster, octopus, chicken and rice.After lunch, roll out a towel on the beach or take a dip in the warm ocean. Snorkelling off the beach is also recommended – the waters here are teeming with tropical fish. You'll round off the day with a short dolphin encounter where you can learn and interact with these clever aquatic mammals.
