Gunner's Quoin, Mauritius
Sailing the Northern IsletsMauritius is surrounded by dozens of tiny islets—and there's no better way to explore them than by sailboat. Experienced sailors can rent their own boat near Trou-aux-Biches (and novices can jump on the nearest catamaran booze cruise) and circumnavigate the stunning landscape of Gunner's Coin (also known as Coin de Mire) and its neighbors.
The water is so clear in spots, you can see brightly colored fish from the boat. And it's likely you'll see a dolphin or two on your journey. But why settle for that? To get the full experience, make sure to stop along the reef for some snorkeling.
