Snorkeling inside an ancient volcanic crater rim — Molokini is a crescent-shaped island 3 miles offshore in the Alalākeiki Channel, with 150-foot visibility and 250 species of fish in a protected marine sanctuary. One of Maui's best snorkel outings.
Why It’s Worth Your Time
Molokini Crater is one of the great snorkeling destinations on Earth — a half-submerged volcanic crater 3 miles off South Maui with water visibility regularly exceeding 150 feet, a sheer crater wall dropping 300 feet, and 250 species of endemic Hawaiian fish. The site is a State Marine Life Conservation District — no fishing is permitted and the ecosystem is among the most pristine in Hawaii. Tours depart from Ma'alaea Harbor. The Pride of Maui and Trilogy Excursions are the best-regarded operators. Book the first departure (6–7am) for the calmest water and fewest people inside the crater — afternoon conditions are often rougher.
What Stands Out
- 150-foot visibility — among the clearest water in the Pacific
- 250 species of endemic Hawaiian fish in the crater
- State Marine Life Conservation District — ecosystem protected
- Book the first morning departure for calm water and fewer boats
- Pride of Maui and Trilogy Excursions — the two best operators
