Feel like cooling off with an underwater view? Grab that snorkel, put on your flippers and get carried away by the crystal clear waters of the Costa Tropical. The corners of La Herradura, the bay at Marina del Este and the rocks at Cantarriján are like an aquarium without glass. Tropical fish, seagrass beds and the occasional squid looking at you curiously. Like the snorkeling? Diving is the logical next step here. And trust us: you really want to experience that underwater world.
