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.

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.

Food and drink avaialble as soon as we boarded and throughout the day. Good snorkeling gear and very efficient set up to get us in and out of the water. On the flip side, It was crowded and the chairs/tables were very close together.

This was a great day trip. Very relaxing, everything you need is provided (for a small fee). Great crew on the Calypso. Very Family friendly tour. We saw a lot of turtles and lots of whales! Snorkeling in a caldera is pretty epic!

First class experience! Well organized, safety issues ,emphasized, crew very attentive. Exiting water much easier than most snorkel trips due to eight ladders being available for snorkel clips and swimmers. High-quality snorkel equipment made for few problems!

Absolutely hands down best snorkeling experience ever. I loved the staff. They were on top of their game and made it fun and safe for all of us. My husband and I had so much fun and the food was great as well.

Everything on the boat was Nicely organized. The crew took care of every one and was very sweet. Was a little disappointed that we didn’t see any sea turtles. The fish we saw were beautiful but limited. We stopped at two places, molokini crater which is where all the fish were and turtle town, but didn’t see any turtles. We ended up seeing a lot of whales which was pretty cool. I probably wouldn’t book again but was a great experience

Amazing snorkeling. Saw lots of turtles and fish. We also got a bonus whale tour as well. So many whales around us and the captain did a great job narrating and allowing us time to view.

Great half-day trip. Plenty of food, friendly staff. We stopped for whales. The $2 cocktails on the way home was a classy touch. Most operators would have overcharged their captive audience.
