Molokini Crater

"An ancient atoll, Molokini lies 2.5 miles off Maui’s south coast, where the water is calm, clear, and teeming with marine life. Here, snorkelers and scuba divers can expect up to 150 feet of visibility, allowing for perfect views of yellow tang, parrot fish, black triggerfish, bluefin trevally, and even moray eels. To explore it for yourself, book a tour with Maui Classic Charters, which sails to Molokini in a 55-foot catamaran with a glass-bottomed viewing room. Choose one of the early-morning trips for a better chance of calm seas and bigger sea creatures like octopus and eagle rays, and bring along snacks, sunscreen, and, for those who run cold, perhaps a rash guard or thin wet suit, especially in the winter months."
