Cheval Blanc Randheli is a luxury private-island resort in the Noonu Atoll, Maldives, built around a Green Star Award-winning, 5-star PADI-certified Dive Centre that runs excursions suited to all levels and interests, including night dives and scooter dives. The Maison also hosts a resident marine biologist, who leads guests through the reef's marine life -- parrotfish, manta rays, sea turtles and sponge corals among them. Guests can snorkel directly from their villas or sail out into the surrounding lagoon and reef with the dive team.
