    Amazing Underwater Experience Without a Splash!!
    Marie_C, Aug 2023
    It was such a cool experience, especially since we had our 1.5 year old who can’t fully swim yet and my grandparents with us. It’s a great option to see the water life without having to snorkel or scuba dive. The staff were great and we absolutely got a kick out of “Crazy” Will. He was so personable and very informative about the ocean life.
    Great morning tour!
    JoAnn_R, Aug 2023
    It was a great experience for all ages! We got to see so many fish and turtles! Wonderful! There were some rowdy kids on our tour but once they got to see the marine life, they settled down. Would highly recommend!
    Good family activity to do in Maui
    Lin_T, Aug 2023
    This is a great family activity to do in Maui. My family enjoyed it. The staff are friendly. They also took a family photo for us before we we went into the sub…still waiting for them to send it to us via email.
    Response from Host, Aug 2023

    Cool experience and great for young kids
    Alex_A, Aug 2023
    Great experience. This was perfect for my family of non and weak swimmers who wanted to experience the sea and did not want to snorkel. We got to see some octopus, coral, various sea life. The divers that accompanied the ship were great. I also appreciated that there was adequate space in the ship and we didn’t feel claustrophobic (as compared to the submarine). I would recommend as an alternative to the submarine experience.
    Good alternative to snorkeling
    Ashley_C, Jul 2023
    This would be good for younger children or older folks who are unable to snorkle, but it was honestly a bit boring for our 4 kids who had already been snorkeling with the sea turtles. The crew was great, but divers had bad luck only bringing up an urchin and a sea star. Not a bad experience for the money, but this was definitely the least enjoyable of all our excursions in Maui.
    Christopher_N, Jul 2023
    Amazing crew fun and very informative had a blast got to see a couple of things and learned some stuff I didn’t know very educational as well
    Not worth the money
    Anja_S, Jul 2023
    The glass bottom isn’t a glass bottom. Small windows. Barely any marine life. Not worth the money at all. You are more snorkeling.
    I would do it again
    Aisha_B, Jul 2023
    Just being underwater, and seeing life underneath!!! It was cool to experience. The kids we're able to ask as many questions as they wanted.
    Affordable fun
    Craig_W, Jul 2023
    Alot of fun and very educational. The crew were very friendly and our guide "crazy Will" was full of dad jokes. Great for people who have never snorkeled or dived.
    Absolutely awesome time

    We had Will for our guide today. Let me start off by saying I've never met a more knowledgeable guide for any tour. He was like Alex Trebeck from jeopardy. He had all the answers and awarded points for good questions. We saw at least 1,500 sea turtles on this excursion under the sea and through the coral reefs. The scuba swimmers were masters of their craft. They collected underwater lifeforms and brought them to the windows, allowing us to view these heavenly creatures in their natural habitats in all their glory. The submarine part of the vessel was cool, not just temperature wise, like it was radical. Cool music playing softly in the background, the wise sage words of our most bodacious guide, Will, guiding us on our undersea adventure. At no point did the spacious underwater cabin feel constricting or cause claustrophobic responses. Everyone had plenty of room to move about and engage with our yogi, Will. Honestly, I'm not sure what was more enjoyable to aquatic views, which were amazing, or the most inspiring of guides who was equal parts google search engine and comedy central special. We saw unicorns, seals, urchins, fish, octopuses, and underwater divers. It is a trip I will be making sure to take every time I return to Maui. You should book your underwater adventure with reefdancer immediately if you haven't already booked it. Also important to note, my kids haven't agreed on anything so far this trip, but they all loved the reefdancer underwater adventure through the coral reef. Rock on dudes.
    Coral, turtles, fish, sea cucumbers, erchins, & stars...oh my!

    Terres_M, Jul 2023
    The children loved, looking out the windows plane from one side of the submarine to the next, and have the capability of seem two sides. We saw sea urgent, turtles, all kinds of fish. The staff was knowledgeable kind and made the ride worthwhile. Definitely every penny you spent will be worth it now book it and have some fun.😎
    This was an amazing...
    NIKKI_M, Jul 2023
    This was an amazing experience. I really wanted my 8 year old to get to see life underwater without having to snorkle and this definitely fit the bill. Saw 5 turtles, 3 stingrays, an octopus, cushion starfish and a ton of fish. Rachel was our guide and did a wonderful job. She was so enthusiastic about everything it made for a great time
    A great time on the water!
    Deja_A, Jul 2023
    What a great experience! We saw many sea turltes, different fish, an octupus, sea urchins and a eel. The tour guide was knowledgeable and the whole staff was super friendly. My kids had an amazing time and it was just long enough to hold their attention.
    The Best Experience!
    James_C, Jul 2023

    Great experience for kids!
    Melissa_A, Jul 2023
    Our kids aren’t ready to snorkel yet so this was a great way for them to see the ocean creatures! We saw an octopus, a shark, a sea turtle, starfish, sea urchin, and of course tons of fish!
    Great trip!
    Natalie_S, Jul 2023
    We loved seeing the turtles and the divers bringing creatures for us to see! It was a unique way to see the sealife!
    Matthew_W, Jul 2023
    Our group ranged from six months to 65 years old five kids. We had an incredible time they were laughing and learned a lot definitely recommend.
    Emily_V, Jul 2023
    The suba divers were amazing and brought three different sea creatures right up to the windows for us to see. They took our picture professionally before we got on the boat and sent the photo to us for free, which is basically unheard of around here. Even though we had a great time as it was, we were given a rain check because the water was a little murky. The staff was super friendly and accommodating. I highly recommend this tour.
