It was quite confusing to find the meetup point at the beginning, but asking the hotel staff did help us getting there. We went on the high-tide day so needed to walk a bit from the usual boarding area. Probably helpful to remind people wearing slippers as you'd need to take shoes off. They did provide proper and plenty storage spaces for your footwear on the boat (appreciated!). Drinks were pretty much bottomless and they had their very own Mai Tai so you could really enjoy the 'complete Hawaiian package'! The only problem with high tide day, it meant be prepped to get wet and going on and off the boat would be quite tricky as you needed to manage timing to avoid the tide from getting you soaking wet. I was unfortunately not the pro and literally got half-bottom wet, getting off the boat LOL. Paid off by the gorgeous sunset view!!

Lola was our main guide and not only was she well educated, attentive, and a great tour guide -- she also would go above and beyond to make your tour incredible. None of the other guides from other companies got off their boards, let alone free dove 40ft to try to get the reef shark to leave its rock so everyone could see it. She also provided many of our crew with their own free dive instruction so that they could try as well. Amazing trip, amazing sights, even better crew!

If you're an energetic couple looking for more than just a relaxing beach day, Island Splash Turtle…read moreTours delivers an experience that's equal parts thrilling, educational, and impeccably organized. From the moment we arrived, their team demonstrated a level of professionalism that immediately stood out. The check-in process was seamless, the safety briefing was clear and thorough, and the equipment was in excellent condition. You could tell they run a tight operation -- everything felt structured, efficient, and well thought out without ever feeling rushed. What truly elevated the experience was how intellectual the tour felt. The guides weren't just there to point out turtles; they shared fascinating insights about marine ecosystems, turtle behavior, conservation efforts, and local oceanography. Their knowledge added so much depth to the adventure. It felt like a marine biology mini-masterclass -- but one where you're actively swimming through the lesson. And speaking of active -- this is not a passive, float-around experience (which we loved). As a very active couple, we appreciated the energy and pace. There was plenty of swimming, exploring, and maneuvering through the water, and the guides kept the vibe upbeat and engaging the entire time. They matched our enthusiasm and made sure we got the most out of every moment in the water. The atmosphere was fun, vibrant, and full of positive energy. The team clearly loves what they do, and that enthusiasm is contagious. We left feeling exhilarated, accomplished, and genuinely grateful for such a well-run adventure--we left having seen many turtles, Hawaiian spinner dolphins, a stingray and plenty of fish in a natural setting. If you're the kind of couple that prefers movement over lounging, learning over just observing, and meaningful experiences over generic tours -- Island Splash Turtle Tours is absolutely worth it. Professional. Knowledgeable. Energetic. And incredibly fun. We would book again in a heartbeat.

Dani, Ben, Faavae, Kania, Roxanne, Kirra, Bernard, and Keely all made the trip special. Keely deserves a special shout-out! The crew provided educational facts, acted as lifeguards, served food and drinks, and even danced, making the whole experience fun, safe, and memorable. I highly recommend this tour to anyone looking for an incredible ocean adventure in Hawai'i. Great service, beautiful wildlife, and an outstanding crew!

Semi-Private Snorkel Tour --7:15 AM Departure…read more If you're debating whether the early departure is worth it-- it absolutely is. Being the first boat out in the morning makes a huge difference. The ocean was calm, conditions were excellent, and we weren't surrounded by multiple tour boats. For long stretches it genuinely felt like we had the reef to ourselves. Sam and Ella were in-cred-ible. Professional, knowledgeable, and very clearly people who love what they do. They struck the perfect balance of being attentive while still letting everyone enjoy the experience naturally. We felt extremely safe the entire time, and they were just genuinely joyful humans to spend the morning with. And I have to mention the turtles. We saw at least eight. Not just in the distance-- they were everywhere. Below us in the reef, gliding past us at the surface, popping up for air unexpectedly. At one point we were actively looking around just to make sure we weren't about to bump into one. Also...calling them "little" would be inaccurate. Some of these turtles were big-- absolutely stunning animals. Swimming alongside them, surrounded by hundreds of reef fish, was one of those rare travel moments that sticks with you. A core memory, without question. -- San Diego
