What Are the Lanai Cathedrals?

The Cathedrals were formed when lava flowed from the neighboring island of Molokai and cooled down on the ocean floor. These lava formations are now home to a wide variety of marine species, including schools of brightly colored fish, large sea turtles, and elaborate coral reefs.

Lanai’s First Cathedral

The First Cathedral is the first site as well as the largest and most popular of these formations, with a depth of around 60 feet. This cathedral is home to more than 300 marine species, including colorful corals and an abundance of tropical fish.

The First Cathedral is a popular spot for all levels of certified divers. The depths range from 12-40 feet, with an average depth of 25 feet. You can swim through the coral garden and lava formations, spotting frogfish, reef fish, and eels along the way. 

There are several entrances and exits in the cavern system, which can be confusing when you dive. Make sure to have a dive plan and follow your fellow scuba divers.

As you go deeper into the Cathedral, you look into the “confessionals” — small side chambers. They are home to resting sharks, puffer fish, crabs, eels, and nudibranchs.

You will exit out the “shotgun” — a small opening at the back of the cave. A “lava shoot” can propel you out of the cavern; however, the timing needs to be just right so that you can exit with a water surge.  

Most dives in the area are 2-tank or 3-tank ones. After your first dive, you’ll get a surface interval on the boat while you travel to Lanai’s Second Cathedral. Your boat will likely offer snacks or a light lunch with both vegetarian and non-vegetarian options.

If doing a 3-tank dive, your third dive may be at a popular dive site like “The Carthaginian,” which sits in around 90 feet of water and is a destination for the Atlantis Submarine, so you may see the sub while on your dive which can be a fascinating experience and include customers in the submarine waving to you on your dive!

Lanai’s Second Cathedral

Like its sister dive spot, the Second Cathedral is an amazing dive site, named “second” only because it’s the second one your boat will take you to. It’s a vast underwater cavern with numerous swim-throughs, archways, and a 6-foot-long black coral fan growing downward from the roof. 

The clear waters and abundance of marine species make it a perfect place for an experienced certified diver and beginner alike. Many of the fish that can be found here are unique to Hawaii, including the Hawaiian triggerfish, which are known for their bright colors and friendly nature.

Second Cathedral is also home to a variety of sharks, rays, and turtles. These gentle giants are often seen swimming lazily through the caverns or resting on the seafloor. 

With its crystal clear waters and plethora of marine species, Second Cathedrals is truly a diver’s paradise.

It’s Not Just the Cathedrals. Explore Other Lanai’s Scuba Locations!

With its beautiful underwater cathedrals, varied species, and dramatic lava shoots, lava tubes, and other formations, Lanai is a must-visit scuba destination. But there’s much more! The south side of the island has over 20 different dives sites, such as:

Shark-Fin Rock

Shark-Fin Rock is one of the most popular diving spots in Lanai, Maui. The rock formation gets its name from its shape, which resembles a shark fin. The spectacular scuba diving spot is known for its dramatic drop-offs and strong currents, which attract a variety of marine animals.

Shark-Fin Rock is also home to a coral reef, which is teeming with several species of colorful fish. Divers can expect to see a wide range of underwater creatures, including whales, dolphins, turtles, eels, and sharks. 

The best time to explore Shark-Fin Rock is during the summer months. Summer is when the water is calm, and visibility is good, especially during the early morning time or the break of dawn.

Steve’s Cave

Steve’s Cave is another popular dive site in Lanai, Maui. Named after Steve, who is a local legend and is known for his explorations of the caves on the island, Steve’s Cave is an extensive lava formation that comes alive with all sorts of marine life. 

This spot is best suited for intermediate and advanced divers, as it has narrow passages, strong currents, and low visibility. However, if you are a skilled diver looking for a challenge, Steve’s Cave can be the perfect place for you to visit.

At the Lanai Cathedrals, you can reach depths from 20 to 100 feet, making the spot perfect for both recreational divers and avid technical divers. Non-certified divers will not be able to dive at Lanai Cathedrals, and Advanced Certification is suggested but not required.

How Can You Get to the Lanai Cathedrals?

Lanai is Maui’s neighboring island. In order to get to the island of Lanai and the Cathedrals, you will have to go on a boat ride from Maui. The most common way is taking a short boat ride from Lahaina Harbor in Maui. It can also be reached via the ferry from Lahaina Harbor; however, it is a very long surface swim from 

It is best to choose a reputable dive shop that offers full-day boat dive excursions to the Cathedrals and other dive locations on Lanai. Be sure to book your spot in advance and be on time, as there are very few dive boats and these boats leave promptly.

Whether you decide to book a trip or rent your own boat, prepare for your dive by bringing all of the necessary gear and equipment. 

What Scuba Gear and Essentials Do You Need to Dive at Lanai?

You will need a wetsuit, diving mask, snorkel, buoyancy control device (BCD), scuba regulator, and a pair of fins. 

You may also want to bring along a compass and a dive computer to navigate the location and measure your depth. Additionally, it is recommended that you bring along a source of light specifically designed for deep cavern and cave dives.

A reputable dive tour operator can provide the rental gear for an additional cost. Make sure you inquire before the tour to make the trip as smooth and enjoyable as possible.  

How to Enjoy Lanai Dive Sites Safely and Sustainably?

To safely and sustainably enjoy your time at the Lanai Cathedrals and any other dive location surrounding the island of Maui, it is important to practice proper diving etiquette.

This includes following safety guidelines. You should never touch or harass wildlife, including whales and dolphins, dispose of trash properly, and respect all local regulations. The crew will give you a short briefing before you suit up and go. So, make sure to pay attention.

You must be a certified diver and have the right certification to dive the depths you want. A great scuba experience also requires the enthusiasm to discover an entirely different world underwater and most importantly, a reputable crew as your guide. 

Good weather is also important. The captain decides where you will dive based on conditions. Since there are few dive boats diving in the area and most boats have small group sizes, you may be the only people there!

Keep in mind that you should have a moderate physical fitness level for this experience. Those with heart problems, respiratory conditions, and other serious medical conditions are not advised to take on scuba diving as it may result in incapacity underwater. The minimum age for a Lanai Cathedrals dive is 12.
