What are people saying about Hawaii

Karen_R, Nov 2026

Great fun.

Crew were super friendly and we always felt safe. We got to see our fair share of turtles and recommend going if the water visibility is clear. Something the crew can't control. Boat is easy to get in and out of. The turtles are there and it's the closest we've every been to them. All in all it was a lovely experience and you're out for the full 2 hours. Recommend doing.

Swimming with the fishies

One of the coolest tours I have done. The guides are wonderful. I do not swim well. They were there to help me get in and out of the boat. The stingray are amazing. The swim right under you. Touching you from time to time. The amount of time in the water. Was just enough. Great experience

Great snorkeling adventure

A fun two hours, well worth it. Saw several turtles and lots and lots of beautiful fish. Particularly appreciated such a small group (5). Some of the boats we saw had a huge amount of people. Maddie was a great guide, very friendly and helpful, and Angi a great captain. Highly recommend.

Best way to spend a day

If you want to see the whole island without having to drive and find everything yourself, this is the way to go!! Eric was funny and knowledgeable. Our whole bus had a blast. We had time for shopping, swimming, pictures, and lunch. Couldn't have been a better experience.

This is quite a sobering...

This is quite a sobering experience. IMO, do not take small children as they don’t understand what they are seeing and many were disruptive. It is a place to reflect on so many who lost their lives. On a more positive note, our driver (the devil) was completely awesome. Patient with kids and so very knowledgeable about 12/7/1941 - I complimented him on his knowledge of the events and he told me he wrote what he speaks. It was quite amazing how he unfolded the story. Highly recommend!!

Molokini Crater Snorkel and Turtle Cove High Quality Adventure!

Sally_H, Oct 2026

Fantastic crew and snorkeling experience!

If you are going to snorkel anywhere, Molokini is a must! The clarity of the water is incredible - And, the crew was friendly and attentive, making sure we were fed and hydrated, assisting with our gear. I highly recommend this tour group! (Quick tip though - if you are on the Norwegian POA cruise, you need to do this on the second day in Maui and keep in mind that this tour takes place on the opposite side of the island (a 20 minute drive).

Great experience

Alex was a great instructor for my beginner scuba diving experience! I was nervous at first, but his support really helped me feel calm and comfortable. I ended up having such a fun and memorable experience! I’d definitely recommend booking a scuba diving experience with them, especially if you’re a beginner!

Oahu Small-Group Circle Island Tour with Turtle Snorkeling

1000/10 tour dè turtle!

I had an incredible day with Tour guide Benji on this small tour of Oahu as a solo traveller from Australia. Weather to start the day post hurricane was atrocious and raining, but Benji did everything in his power to make sure it was still memorable! When we couldn’t see any turtles snorkelling due to the quality of the water, he drove to every beach and secret location to ensure the people on the tour who hadn’t got to see a turtle, got to experience that! Ultimately finding us the biggest turtle sunning itself on a secluded beach - incredible! Benji was always super accomodating, happy to chat and take photos of everyone and by the end of the the day, the positive energy of the experience brought out the sunshine and we all got burnt, a major turnaround weather wise from the start of the morning! I was 10000/10 recommend this tour to anyone visiting Waikiki, especially if Australian!!

Fun ride out to the bay....

Fun ride out to the bay. Snorkeling was good. Smallish area which was manageable and we saw a lot of fish and coral. We were out about an hour which was a little long. Would be good for kids or newer snorkelers. Eric and Lucas were good guides. You don’t need anything they try to upsell you on at first.

Waikiki 2 hour Turtle Canyon Snorkeling Adventure

Roxanne_L, Aug 2026

Terrific Turtle Time!!!

Captain Mo of Pink Sails and her trusted crew of turtle whisperers were absolutely incredible! We had the best 2 hours on the open ocean and encountered many majestic turtles and colorful tropical fish while snorkeling and also pods of playful dolphins during our sail back to shore. Captain Mo was so kind and thorough on rules and safety and shared a wicked sense of humor throughout. Special shout out to “Little Dog” who spent some time with us during the sail. Adorable! Helpful crew member, Sheamus, guided us from his surfboard to all the best spots on the reef to see the turtles and even spotted a baby turtle for us. Beautiful experience to explore nature and the bounty of its precious creatures. Our daughter, who now lives on the island, is taking her boyfriend on another Pink Sails tour as she wants to further share the experience with loved ones. We hope you will too…don’t miss this special island adventure while visiting Oahu. It’s priceless! Mahalo Pink Sails…you are a blessing. We hope to come back soon! Roxanne L and Ohana

Best Experience of Out Family Vacation

This is hands down my favorite thing we did on my family’s vacation. There were only 6am time slots available, but waking up early was worth it. Our driver Mark was friendly and informative. The gear was great, better than other snorkels I’ve used and easy to get the hang of. We booked this last minute since we weren’t able to get tickets to the park via the official website, but my experience with this tour was so great, if I were to visit again, I’d just skip the hassle of trying to book via the official website and go with Viator.
