I really wanted to enjoy this tour, but unfortunately didn't have a great experience. It was very…read morewindy and the water was extremely choppy. Multiple guests were getting seasick, as the Captain tried his best to navigate the waters. One guest nearly fainted and after that, the atmosphere on the boat changed. The Captain wasn't talking much and it seemed as if he just wanted to get back to the dock. Knowing the weather conditions, I wish the tour was rescheduled. We saw some fish and barely saw a turtle. I know the tour doesn't guarantee seeing wildlife, but it was disappointing hardly seeing anything in the glass bottom. To add, the glass bottom is just 4 boxes that you have to peek over to see. I didn't get seasick, so it was still nice to be out on the water and enjoying the views of the ocean. Prior to the incident, the captain was very educational and funny. Overall, had the tour been on a different day with more permitting weather, I think it would've been great.

They also offer a military discount, which we really appreciated. Once we got out on the water, the experience was unforgettable. We swam with colorful fish and sea turtles, saw dolphins, and even got to see false killer whales. It was truly a great day out at sea. The crew was exceptional: Capt. 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!

This tour is very misleading online snd I want to make sure ppl know what they are signing up for…read more The staff was wonderful and very organized. But despite being called a "Dolphin and You" tour, there is only dolphin WATCHING from the boat -- no swimming with dolphins. They also only stop at one snorkel spot in shallow waters.m whereas most companies have you snorkel at 2. Maybe if I had never been on another tour, I would have thought this was good, but I'd only recommend this for people who want to mainly watch things from the boat and not snorkel. I honestly saw more marine life where I live in OC. On a previous tour with a different company, I swam in waters where dolphins were swimming all around and underneath me -- it was a core memory, and I was hoping to recreate that experience. They also don't let you swim very far from the boat, which made the experience feel overly restrictive. Because the website is not clear I will lay down the iternary: 6:00am pick-up from hotel (about 1.5 hrs to get there) Restroom stop at Fareharbor 1 hr dolphin watching--basically your just on a boat 1 hr snorkel--will see sparse fish 1 hr return--will give you sandwich and water cups no water bottles, temporary tattoo offered Return to hotel: another 1.5 hrs to drop everyone off etc Kind of waste of money $180+ and my precious vacation time. Also, be wary of the reviews. They offer incentives for leaving one. Sorry, but as a Yelp Elite, my honest opinion can't be bought.

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.

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
