About the Tour

Rated as one of the top 100 dives in the world, the Cathedrals are a “bucket list” dive for any scuba diver. The two dive sites we call Cathedrals are vast caverns where rocks have fallen from the ceiling allowing sun rays to shine through the crystal clear water creating a church-like experience. There's no need for a cave or cavern specialty to enjoy Cathedrals as these caverns are accessible for proficient Open Water divers. Besides being dazzled by the Cathedrals themselves, divers can expect to see healthy corals, nudibranchs, octopus, sponge crabs, frog fish, eels, endemic fish, and reef sharks.

In addition to the Cathedrals, Lanai is host to 20+ other fantastic dive sites. We love diving the unique underwater topography of caverns, lava shoots, swim throughs, and arches that are shaped by the island’s volcanic past – and you will too! Every Cathedrals 2-tank boat trip begins with a dive at another site on Lanai to help divers get comfortable in the water before entering the caverns but that doesn’t mean these are not world class dives in their own right. Expect to see healthy corals, nudibranchs, frog fish, octopus, turtles, reef sharks, eels, endemic fish, and more at these sites.

Your experienced captain will determine the days sites based on conditions but you can expect to dive Lanai’s famous Cathedrals along with other locations. Our group sizes are small and you will receive special attention from your instructor who will guide you on 2 exceptional dives and answer all of your questions about the marine life. Dolphins and whales are frequent visitors and we always stop when they are spotted.
