Feb 2026 - Based on my experience, I urge you to consider not doing business with this company…read more They appear to value revenue over the safety and comfort of their customers. Due to hazardous weather conditions, the tour we were on should never have left the harbor. Not only were the ocean wave conditions reported by the coast guard to be clearly dangerous, the driving hard rain made the conditions completely unacceptable not only for safety reasons but for customer comfort. Despite my several attempts to point this out to the staff answering the phone one day prior to the tour as well as the captain of the boat prior to departure, they blocked my attempts to reschedule or refund the trip in spite of coast guard and national weather service small craft warnings, beach closures and other tour operators canceling their tours under the same conditions. After waves broke over the bow of this small craft, the captain aborted the tour and turned around. After an unusually leisurely return to the dock, I called and asked for a refund. Later we were told based on our return time, we had received the full tour and a refund would not be issued. After escalating our concern, a senior member of the company emailed us and said we would be issued a full refund. Over six weeks later they have still not issued us a refund. We had to file a dispute with our credit card company.

Good company to dive with out of "A" Bay, but I am not fond of the dive sites north of Waikoloa…read more My family and I were staying up at the Hapuna Beach Prince Hotel and the 10 mile drive down south to hop on the Lani Kai was really convenient. I booked the trip through Ocean Sports that has a shack on the beach at "A Bay" also known as Anaeho'omalu Bay. My sister has lived on the Big Island for a few decades and I visit quite often, but I still give up on pronouncing most of the Hawaiian names. DIRECTIONS TO A BAY: If you are heading south from Hapuna Beach turn right at the second light which is Waikoloa Beach Drive. Go past Marriott and make a left when you see Kolea Resort. There is a gate, but look to the left and you will see the public parking lot. Park and walk down the path through the lava field and you'll see the Ocean Sports Beach Shack. Check in there and you'll see the Lani Kai sitting in the water. See my photos. WEBSITE: http://www.waikoloacoastdivers.com PHONE: (808) 895-8387 MY TRIP DETAILS: Date: Thursday, August 23, 2012 Time: 8:00 a.m. to noon COST: $177.00 for two tank dive, including the gear. Walked out into the water and boarded the Lani Kai. Met James and Brooke and we headed north to our first dive site near Puako. All the wet suits, tanks and BC's are provided. James Bach was our captain for the day and Brooke Landt was the Dive Master. Captain James headed north toward our first dive site. On the way there we saw a huge pod of dolphins and we all headed to the bow to take photos. Our first dive site was near Puako. It wasn't my favorite place, but we went through some lava tubes. I don't recall seeing any memorable sea life while down below. James and Brooke caught two big Ono on our way to the second dive site near the Hilton Waikoloa. We saw a blacktip reef shark and some Horned Helmet Snails which were cool during our second dive. I think the next time I go diving on the Big Island I will concentrate on sites south of Kailua-Kona because I think the sites are much better. The Lani Kai was convenient for our hotel though, so we didn't have to drive an hour or more to board one of the vessels down south.

We've done morning dives, the manta dive, as well as the twilight and night dive and every experience has been incredible. The staff is fantastic and always takes such great care of us. I would recommend this shop to both new divers and seasoned divers alike. We've met some really amazing people through these trips and every outing has been organized, safe, and genuinely fun. The boat is spacious, they provide snacks and drinks during the surface interval, and they handle all of your gear setup which makes everything so easy and stress free. The team is super knowledgeable and does a great job grouping divers based on experience level so everyone has a good time. I'd also love to give a big shout out to Daniel and Cody who are always a blast and so much fun to dive with. Maxine is an awesome boat captain and Ashley was incredible dive master as well. She led our manta dive a year ago, gave such a great pre dive presentation, and was super thoughtful and fun to dive with on two separate occasions. Honestly, because of this dive shop we keep coming back to the Big Island and continue rebooking with them every trip. Highly recommend and I wouldn't look anywhere else for diving in Kona!

Our diver, Bradly, said that Hannah did a great job as his dive instructor, and she was great at helping the newest diver of the group who was heavily struggling during his dive. Myself and Lisa were snorkeling with Laura and she was very helpful! She was great at finding mantas for us even when they wanted to hang out by the campfire. Chad, our captain, was super friendly and talkative. I get extremely motion sickness very easily. The waters were extremely rough during our visit, and I did get sick during the last five minutes of the snorkel, as well as the boat ride back. All members of the staff were very understanding and kind, and made it very clear that if I had to return to the boat during the snorkel or did have to hurl during the ride, they wouldn't be upset or judge, and wanted to help me in any way possible. A super nice and interactive crew, and they shared lots of stories about the rays that frequent the area we explored! We were lucky enough to see two bottlenose dolphins (a mother and child), a Galapagos shark, 4-8 rays for the snorkelers and 11 rays for the divers. I highly recommend booking through Big Island divers! They provided all of the equipment needed, and we were welcome to wear/use our own if it made us more comfortable. The only request I would make is that the snorkel instructor be more adamant about keeping our feet up straight in the water, as the two snorkelers across from me on the board constantly had their feet in the water as if they were doggy paddling, which over rated our view of the marine life and caused the board to shake (increasing my motion sickness). I chose not to wear fins because I had gotten anxious while wearing them earlier in the day, but I kept my feet up the whole time because of my previous snorkel experience . It would have been really helpful to have our snorkel guide get those guests to keep their legs up, but otherwise every staff member did amazing! Chad let a young girl steer the boat for a while which was really kind.

The DMs &…read moreBoat Captains were amazing, their customer service is incredible, gear was great, excellent communication and attention to safety. And I had a ton of fun. I will definitely be diving with them again. Thank you Natalie, Lauren, Haley, Emily, and Nick for the incredible experience! Full Review: I booked the two-tank Manta dive and the two-tank morning dive. I'm still fairly new to diving--I was certified about a year ago, and these were my first dives since then. Check in at the shoot was a breeze, and they introduced me to the Divemaster for that day's dives, Natalie. I told her I was a bit nervous and still rusty with things like buoyancy control. She immediately reassured me, told me I'd stay close to her, and said, "We've got you." I rented gear through them, and they handled everything, including bringing it to the boat and setting it up. Our boat captain that day was Nick, who was fantastic. He gave a thorough safety briefing but also brought a lot of personality and humor to the trip. It was clear how passionate he is about diving and the marine life. Throughout the trip he was constantly sharing stories and information, and his enthusiasm really added to the experience. Our group had six divers and two Divemasters: Natalie and Lauren (a DM in training). It was great being in such a small group with two guides. Natalie gave an excellent orientation before the first dive, covering safety, the dive plan, and what we might see. I had a little trouble descending at first, but she was incredibly patient and helped me relax and get started. Early in the dive Natalie pointed out a Galápagos shark--so cool! We also a bunch of eels, a nudibranch, blacknose butterflyfish, and more. I stayed close to Natalie while Lauren brought up the rear of the group, and it felt great knowing both of them were keeping an eye on everyone and pointing out marine life. Lauren led the manta dive that night. After another great briefing, we descended and the dive was incredible--we saw around 15-20 mantas (which is way more than the average). They were beautiful, and the whole experience felt magical. Fifty minutes went by in what felt like ten. On the ride back, Nick turned off most of the boat lights so we could enjoy the stars on the way in. The next morning I dove from a different boat with Captain Emily, who was also fantastic. Our Divemaster was Haley, and Lauren was assisting again. Once again, the crew took great care of everyone. Two guests became seasick on the way to the first site, and Emily and the DMs handled it with kindness and professionalism and without making anyone feel judged. That same pair had some difficulty during the dive, and the Divemasters were constantly checking in and helping them underwater, while still balancing leading the rest of the divers. One thing I really appreciated was how they managed air consumption. They regularly checked everyone's PSI and gave clear instructions ahead of time about when someone should head back to the boat. If a diver reached that point, they could surface while the rest of us continued the dive. That meant those of us with more air could stay down longer and keep exploring. On the way back from the final dive, Emily spotted dolphins and took the boat over so we could watch them surf the wake for a while--a great way to end the trip. All the dives were fantastic, and I can't say enough good things about the entire team. I can't wait to come back and dive with y'all again!

Scheduling the three days of diving with Mike and Liquid Cosmos Divers was very easy and Mike kept in contact with us through the entire process. We met Mike and Jess at the boat ramp, which was easy to find with ample free parking. Their boat is very clean and you can tell that Mike and Jess put a lot of time and thought into the design to make it comfortable and very safe for diving. Although Mike offered to put our equipment together, he had no problems letting us put the equipment on the aluminum 80 cylinders filled to the rated pressure with Nitrox. Before leaving the harbor, Mike conducted a concise safety briefing. During this briefing, my family could tell that diver safety and comfort were very important to both Jess and Mike. As we got close to the dive site, Jess did an amazing job describing the types of animals we might see at the site and how to recognize them. Underwater Jess used an erasable slate to write information about the animals we were seeing and why they were important. My 14 year old son loves learning about the marine environment and Jess taught him so much in the three days of diving. Jess is an amazing dive guide and dive professional and my family and I loved diving with her. Although I cannot predict future dive or sea state conditions, in June of 2026, we had calm seas, 80 to 90 feet of visibility and warm water temps between 77 and 78 degrees. We saw dolphins, sharks, puffer fish, several rare or endemic species of reef fish, multiple eels, nudibrachs, and schools of barracuda. The coral was in great condition and Mike and Jess took us to a location that had coral for as far as we could see. Mike is a great boat captain, diver and water guy and placed us directly on each dive site and then safely picked us up. The boat has prop guards, which made me as a father happy, and a warm water shower that made my wife very happy. Between dives, Mike brought out apple bananas, papayas grown by his house, and vegan muffins that were very tasty, while Jess conducted a comprehensive debrief on what we saw during the dive. I could tell that being friends with the environment was very important to Mike and Jess and no trash or waste was ever thrown overboard. Mike and Jess make sure each diver has their own stainless steel water bottle to keep waste to a minimum and to keep the divers hydrated. The boat has plenty of dry storage, plenty of shade for the divers, and a ladder that is easy to climb. When my family returns to Hawaii we will definitely be going back out with Liquid Cosmos Divers.
