A must for visitors of all ages, this is the only underwater National Park in the world. A clearly marked underwater trail introduces you to a fascinating undersea world of coral, plant life and a variety of tropical fish. Tour boats provide half or full day sails. The full day lets you enjoy the great snorkeling as well as the most beautiful of all beaches. Pack a big picnic lunch, and share some bread crumbs with the fish--they'll really cluster around!
