Molokini is a partially submerged volcanic crater off the coast of Maui, Hawaii, celebrated for its crystal-clear waters, vibrant coral reefs, and abundant marine life.
Molokini Crater is the eroded rim of a volcanic cone that last erupted thousands of years ago, leaving behind a distinctive crescent shape that now shelters one of the most visited snorkel and dive sites in the Hawaiian Islands. The crater sits within a State Marine Life Conservation District, meaning fishing and the collection of any marine organisms are strictly prohibited, which has allowed its reef ecosystem to remain remarkably intact over decades of visitation.
The shallow inner basin, ranging from roughly 10 to 40 feet in depth, is ideal for snorkelers of most skill levels. Colorful parrotfish, Moorish idols, and dense schools of goatfish move freely through the coral gardens, largely unbothered by the steady stream of visitors. For certified divers, the outer back wall plunges dramatically to depths well beyond recreational limits, where hammerhead sharks and manta rays have been spotted on fortunate dives.
Most visitors reach Molokini by joining a morning snorkel cruise departing from Maalaea Harbor or Kihei Boat Ramp on Maui. Trips typically combine time at the crater with a second stop along the Maui coastline, often at Turtle Town near Makena, where Hawaiian green sea turtles rest on submerged lava formations. Onboard naturalists on many boats offer context about the crater's geology and the species you are likely to encounter.
Molokini rewards visitors with a concentrated, accessible encounter with Hawaii's marine environment that is difficult to replicate elsewhere in the islands, making it a centerpiece of any Maui itinerary focused on the ocean.
Visit during the morning hours, ideally before 9 a.m., when winds are calm and visibility tends to be at its clearest.
Bring a wetsuit or rashguard even in summer, as the water inside the crater can feel cooler than expected once you are in the shade of the walls.
Try snorkeling along the back wall of Molokini on a guided dive trip, where deeper, more dramatic drop-offs attract larger pelagic species.
Pack seasickness remedies if you are prone to motion sickness, as the open-water crossing from Maalaea Harbor or Kihei can be choppy in the afternoon.
Look for humuhumunukunukuapuaa, Hawaii's state fish, darting among the coral heads in the shallower sections of the crater floor.
