Mobile ticket
Explore the natural wonders of Molokini Crater, a volcanic islet 3 miles (4.8 km) off the coast of Maui, on this snorkeling tour from Maalaea. Surrounded by clear tropical waters, this extinct cone is home to many species of marine life, such as fish, sea urchins, sharks, manta rays, and coral. Molokini is a marine preserve, meaning nothing can be disturbed, keeping the island and underwater environment pristine. You'll also explore Turtle Town, and admire native birds. Two water slides, a glass bottom viewing room, and a "leap of faith" are also available if you don't want to snorkel or finish early. Breakfast, lunch, snacks, soda, and juice are included.

What To Expect
A tour with the Calypso is one of the most fun on Maui! This stable, high-speed, triple-decker catamaran will get you to two snorkel sites fast: Molokini Crater and Turtle Town, and with all the equipment you need and plenty of food on board, what more could you ask for? The Calypso leaves from Ma’alaea Harbor, and after you are welcomed aboard by your friendly crew, you can take a look at the delicious continental breakfast. After everyone is settled in, it’s off to the most popular underwater destination in Maui for some Molokini snorkeling! While you are enjoying the feel of the ocean wind in your hair. Molokini Crater is located between the islands of Maui and Kaho’olawe. This beautiful site is not only home to several fish species, but many species of birds, as well! The crater is a designated Marine Life Conservation District and bird preserve, so no fishing or climbing on the crater is allowed, but wearing flippers and a mask to watch the fish is perfectly wonderful. After your Molokini snorkeling, Calypso will whisk you to Turtle Town – a second snorkeling spot. Off the south side of Maui, Turtle Town is home to several large sea turtles as well as dynamic reef fish.

Family snorkel trip

5.00We were a family of 13 aged from 12 to 75 and everyone had a great time. We had gone on this snorkel trip in the past liked it so much we took it again. A little difficult seeing the turtles everyone grouped together.
Beautiful blue water. Tons of fish. Excellent crew.

5.00The crew was very efficient. The boat holds over 100 ppl. And was fully packed. So if you don’t like crowds. This is NOT the snorkel excursion for you. Lots of kids on it as well. Good for families- but get there super early to line up for check in. Otherwise you might not get seated together.
Book this trip for an amazing trip

5.00What an amazing experience, the staff was professional, informative, and entertaining, the food was great, drinks are cheaper than a soda, and boy what amazing fish, sharks and turtles you will see. The cruise is relaxing, the boat is perfect and not crowded, the staff is nothing short of amazing. Definitely would recommend for any experience of swimmers, I had an injury before booking and they accomplished getting me safely in the water and made my vacation experience totally worth it! Much thanks to the crew and staff, Mahalo!
Great trip

5.00A truly beautiful experience. We were able to swim near the reef, see dolphins off the bow of the ship, and float as turtles swam near us. Crew was helpful and friendly. Would highly recommend this experience to everyone. Plus the Mai Thais weren’t bad!
Thankful kid on his birthday!

5.00The captain of the boat made customer satisfaction his goal (along with safety obviously)! He made calls quickly to help everyone get to snorkel with turtles, which was what we were after. The food was awesome and we left full! Very thankful for this experience!

5.00This tour was a 10 out of 10. The boat was beautiful clean and well maintained. The staff was friendly and knowledgeable and took the time to get to know you and make you feel at home. We snorkled at 2 different locations and had plenty of time to soak in the beautiful reefs and marine life in the area. We were even lucky enough to see dolphins and sea turtles. Truly the best experience and top notch customer service. Book this trip and you will not be disappointed.
Would highly recommend
