Why Visit Molokini Crater
Molokini Crater is a crescent-shaped, partially submerged volcanic tuff cone rising 160 feet above sea level and 330 feet from the ocean floor, located three miles off Maui's southwest coast in the Alalakeiki Channel between Māʻalaea Harbor and Kahoʻolawe.[1][2][3] Formed 230,000 years ago through underwater eruptions from Haleakalā that cooled into volcanic glass, its eroded northern rim creates a sheltered inner lagoon with 20-50 foot depths, over 100 coral species, 250 tropical fish, and visibility exceeding 100-150 feet.[1][3][4][5] Accessible only by boat from Māʻalaea Harbor or Kihei Boat Ramp, it serves as Hawaii's only island marine sanctuary, ideal for snorkeling and diving year-round, though summer (May-October) offers calmer waters and fewer crowds than winter whale season.[1][2][7]
