Scuba diving in Roatan is worth it, yes. Roatán is situated on the second-largest reef system in the world—the Mesoamerican Barrier Reef—thereby providing clear waters, colorful coral reefs, and diverse marine life that includes turtles, rays, and whale sharks. Such places as Mary and Blue Channel are known all over the world as part of the dive sites. The island is also cheap in terms of dive packages, has warm water throughout the year, and is suitable for all levels of divers. Roatán has great visibility in the undersea life, and it's a must-go destination in the Caribbean as either a first-timer or a professional diver.
