Hotel guests usually stay put once they have settled into their island, but sailing opens up some wonderful opportunities for underwater exploration. The Maldives is made up of 26 coral atolls (ring-shaped reefs) which are home to more than 1000 species of fish, sea turtles, whales, and dolphins. The multi-colored fish and coral are a sight to behold, and the water is so warm many people don’t even bother wearing a wetsuit.
