Visit Maui’s famous snorkeling and diving destinations Molokini Crater and Turtle Town (or Coral Gardens) on a snorkeling catamaran! Molokini is an extinct volcanic cone and the snorkeling visibility is usually 100 feet or more! Many different species of marine life live within Molokini. Green sea turtles, fish, urchins, harmless sharks, manta rays and coral surrounded by crystal clear water all year around make Molokini a must do on your vacation activity list. This boat tour is on all tourist must see lists, and it's one of Maui's favorite activities. This is also one of Maui's most family-friendly activities.
