Certified Scuba Diving at Lanai Dive Sites

Lanai Scuba Diving

The Lanai Scuba Diving is currently unavailable for the foreseeable future due to the damage Lahaina Harbor sustained during the 8/8/2023 fire. For the latest on West Maui's recovery and the availability of tours, see our Lahaina Fire Recovery page.


  • Excclusive dive charter limited to 11 per trip.
  • Certified divers only; excellent gear included
  • Spectacular Lanai dive sites like the underwater grotto called "the Cathedrals."
  • Sharks, rays, eels, and a host of marine life seen regularaly.


Lanai scuba is a diver's delight … the most famous spot is the Cathedrals, a volcanic grotto that is two stories tall inside! The light coming in through the numerous openings creates a supernatural effect – like the light coming in through the stained glass windows of a cathedral. Keep an eye out in the nooks and crannies for lobster, nudibranchs, eels and the white tip sharks that frequent the area. Dolphins, manta rays and eagle rays are frequently seen as well. A second dive spot will be chosen on the day of your tour – very often one of the turtle hang-outs is a popular choice. Most dives average 60 feet. The boat has a fresh water shower, separate rinse buckets for cameras and dive gear, plenty of room on deck and lots of shade.

There are also night dives available, and these are shore dives done at various locations along Maui's west coast.

Extended Horizons has added a 1.83% fee to support "green" initiatives such as day use moorings, biodiesel, and educational outreach. This 1.83% fee and the regular 7.167% harbor/sales tax will be added to the published rates.

Kevin's Activity Tips:

When booking scuba diving plan your dives so that they don't overlap with activities that involve high altitudes. If you plan to do the downhill bike tour, a helicopter flight, trips to other islands or just driving to the top of Haleakala, it is best to do those things first before you begin your diving. While it is more important to avoid high altitudes for 24 hours following your diving, many of the dive companies will require you to be at sea level for a full 24 hours before you begin your diving as well.

Health concerns - most certified divers have had their health problems already screened, but if you have a history or asthma, bronchitis, or other breathing disorders, are on any prescription medications, have problems with ear infections, neck or back injuries, smoke, consume significant quantities of alcohol, or are in otherwise poor shape it is important to address these issues before committing to a dive trip. If you sign up and then are disqualified on the day of your dive because of an obvious health concern the boat may not authorize a refund (because they were holding space for you that they don't have a chance to sell to anyone else). Please Please PLEASE disclose any and all health concerns in the box provided on the reservation form. The list above is by no means complete … ANYTHING other than perfect health should be disclosed. We will contact you to get more details when appropriate; a divemaster will make a determination about your particular situation.
