A boat slips into a bowl of color and light—the sea inside the Blue Cave feels like an opened jewel. Visitors arrive by boat to a narrow cavern where sunlight slices through a small opening, turning the water a luminous sapphire. Instructors brief small groups, hand out masks and fins, and guide swimmers into calm, warm waters alive with parrotfish, damselfish, and the occasional green sea turtle cruising over coral ledges.
