The Maui Diamond Sea Sports Lanai Cathedrals dive is listed as a 2-tank boat dive for certified divers crossing from Maui to the Cathedrals lava-tube caverns off Lanai, a half-day trip. It would suit certified divers wanting Lanai sites from a Maui boat. The biggest drawback: we found no price, schedule, policy or review for it anywhere.

Our Verdict
Tripreviewall's Take
We cannot recommend for or against this dive because no operator page, reseller listing or review for it was reachable in October 2026, and the booking record supplied to us carries no FareHarbor item. Certified divers interested in the Cathedrals should contact Maui Diamond Sea Sports directly for price, departure harbor, schedule and cancellation terms, and compare them with the other Lanai Cathedrals 2-tank dives on this site that do have verified details.
