As the first boat to arrive at the crater, the waters will be uncrowded. Here, you'll also enjoy a delicious continental breakfast. Water visibility at this prime diving and snorkeling spot often reaches 180 feet (55 meters)! If you need a break, relax on the boat’s comfy pontoons and soak up the sun. After snorkeling in the crater, head to the backside of Molokini Crater, a place many people rarely see, for another snorkeling experience.

On your way to your final snorkeling destination, 'Turtle Town,' hug the Maui coastline and view the island’s most recent lava flow on the way to beautiful La Perouse Bay. The bay is a natural habitat for the Hawaiian spinner dolphin, so keep a look out and get your camera ready!

Such an amazing morning of snorkeling. We stopped in 4 different locations and each was so unique. Haven’t downloaded the photos from our GoPro just yet but it was absolutely epic. Tony, our captain, was hilarious, and Lotta was so sweet & helpful. The cinnamon rolls, fruit, sandwiches, chips, and cookies, were all delicious and you can tell the cinnamon rolls, sandwiches, and cookies are homemade. This experience was definitely a 10/10 and we even had a 12 foot tiger shark 🦈 swim by us when we were at turtle city. 😍 What an amazing experience!

Our time with Red Line Rafting was awesome! We took the five hour tour and had multiple drop offs to snorkel. Along the tour we saw tons of sea turtles and whales. It was great!

This crew was exceptional. We had a wonderful adventure and enjoyed each site. Definitely take the 5hr tour as the variation in the sites is dramatic.

Hands down, best experience in Maui. We saw a shark, dolphins, whales, turtles - we saw the sunrise over amazing blue water. We snorkeled on the BACK side of Molokini, which is a uniquely amazing view of deep blue water and brightly colored fish. Tim and Jordan were absolutely amazing hosts/captain/crew! They were informative, helpful, and very entertaining. I’ve been on other boat/snorkel tours but this one beats them all! .

This trip was awesome from start to finish! The captain and crew were amazing! They took us to great snorkeling spots inside the front and back of Molokini. Then we went whale watching before our next snorkel spot among so of the most spectacular coral formations. Our last stop was TURTLES!! On our way back to the harbor we saw 2 more whales showing off for us! It was a great day! I highly recommend this company!!

Our family had a great experience with Kelly and Chase on the 5-hour snorkeling trip. We saw amazing wildlife in the water (tropical fish, eels, lobsters, and sea turtles) and finished off by hanging out with a playful pod of spinner dolphins. I was worried that the trip would be too long, but the time just flew by. Extra bonus for the entire Redline crew for helping us with some car trouble after the tour. Highly recommend!

I had an absolutely wonderful time on Redline Rafting’s Molokini snorkeling tour. From the moment I checked in, the crew made me feel welcome and excited for the adventure ahead. Their friendly service set the tone for the whole morning—warm smiles, easy conversations, and the kind of hospitality that instantly puts you at ease. The ride out was full of laughter, great music, and just the right amount of adventure to get everyone hyped for the day. Once we arrived at Molokini, the team really shined. They were incredibly knowledgeable about the reef, the wildlife, and the island’s history, and they shared it all in a way that was fun and engaging rather than scripted. Their guidance made even first-time snorkelers feel confident, and the entire group had a blast exploring the crystal-clear water together. It was one of those rare tours where you could tell the crew genuinely loves what they do—and their energy made the experience unforgettable.

Great boat tour, unfortunately had bad weather with waves too high, were at Molokini Crater, but with 2.5m high waves no snorkeling possible (bad luck, Redline can't help it), then 2 times breathtaking snorkeling at the turtles, that was absolutely incredible ! Excursion somewhat shortened for the above reasons. Could have done Molokini again for free (just unfortunately didn't have time). Therefore receive unsolicited high partial refund (respect!), also great crew on board and overall super provider
