Clear visibility: Visibility often exceeds 70 feet, allowing divers to fully appreciate the underwater scenery.
Diverse marine life: Expect to see sea turtles, rays, groupers, and a wide range of tropical fish.
Protected marine parks: Many dive sites are within protected areas, ensuring healthy coral and abundant wildlife.
