This catamaran cruise takes you to a series of beaches and landmarks that can only be reached by boat, with time to soak in the island’s volcanic hot springs, too. Plus, with two tour times to choose from and round-trip transport, food, and snorkeling gear all included, this tour is extremely convenient for any traveler wanting to add it to their itinerary.
