Molokini Crater – Hawaii – Maui & Lanai
Site Overview
Molokini Crater is a crescent-shaped submerged volcanic caldera located three miles off Maui's south coast, consistently ranked among Hawaii's premier dive sites with extraordinary visibility often exceeding 30 meters. The sheltered interior crater supports dense tropical fish populations, whitetip reef sharks, and seasonal manta rays in crystal-clear water protected as a marine life conservation district. The advanced Back Wall drift dive on the crater's outer edge provides thrilling encounters with hammerhead sharks, pelagic species, and dramatic 100-meter walls dropping into the deep ocean. The unique volcanic geology creates a natural amphitheater underwater with coral gardens on the inner slope and dramatic drop-offs on the exterior walls supporting incredible biodiversity. The marine life conservation district status established in 1977 has allowed fish populations to recover from historical fishing pressure creating extraordinary biodiversity within the crater walls. Researchers have documented over 250 fish species within the crater including several endemic Hawaiian species found nowhere else on Earth. The unique crescent shape creates natural current patterns that concentrate plankton attracting filter-feeding species including manta rays and whale sharks seasonally. The crystal-clear water results from the crater's offshore location away from sediment sources making it consistently one of the best visibility dive sites in the Pacific.
Dive Briefing
"Descend into the crater's sheltered interior where coral gardens slope from 3 to 20 meters with dense tropical fish communities and whitetip reef sharks resting on sandy patches. The inner crater wall provides excellent macro life including nudibranchs and endemic Hawaiian species. For advanced divers, the Back Wall drift begins outside the crater at depth with the current carrying you along the outer wall with pelagic encounters and dramatic topography. The morning dives offer the calmest conditions and clearest visibility. Multiple mooring buoys allow different dive profiles across the crater. The multiple mooring buoys around the crater allow different dive profiles on each visit ensuring variety for repeat visitors. The interior reef slope features cauliflower coral formations and cleaning stations where green sea turtles pause for parasite removal by smaller fish. The Back Wall entry point requires careful timing with the current to begin the drift safely. Maintain good buoyancy throughout the dive to protect the reef and ensure a safe ascent. Monitor your air supply and depth regularly especially during the deeper portions of the profile."
