Explore Lanai’s famous Cathedrals, lava formations, and swim-throughs on two guided dives from Maui with a small group of certified divers.

About this tour

Discover Maui’s underwater world on a two-tank boat trip to Lanai, where ancient lava flows have shaped dramatic caverns, arches, lava shoots, and swim-throughs. This Maui 2-Tank Lanai Cathedral Scuba Dive gives certified divers the chance to explore the island’s celebrated Cathedrals and other sites selected by the captain according to the day’s conditions.

An experienced crew guides two dives and shares insight into the marine life. Small groups, capped at seven divers, make for a more personal outing. The custom-built boat Hoku crosses the channel, where dolphins and whales are frequent visitors; the crew stops when they come by. Water and a light snack are provided, and SCUBA equipment is available to rent.

The trip lasts about six hours. Divers need Open Water certification or higher, must have dived within the past 18 months, and should be comfortable with moderate physical activity. Meet at the shop on Front Street near Cannery Mall and arrive on time, as the boat leaves promptly. Book your Maui 2-Tank Lanai Cathedral Scuba Dive for a memorable day beneath Lanai’s striking volcanic formations.

How this score is calculated

This score is based on one provider. Viator rates it 4.91 from 618 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Maui
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 8.5. Top 15% in Maui means it ranks in the top 15% of tours in Maui by this score.
