Hol Chan and Shark Ray Alley
Visit Hol Chan where you will see splendid marine life and a large coral garden with stag horn corals and sea fans. Hol Chan meaning 'Little Channel' in Mayan is a natural break on the barrier reef where the ocean is between 3-30 feet.
Shark Ray Alley has shallow water so you will be able to snorkel here and enjoy swimming with harmless nurse sharks and southern stingrays.
You can spend the rest of the afternoon relaxing or exploring the island on your own.
