Traveler Tips

Do bring your own towel ( and wet suit if you like to stay warm in the water).
Give yourself plenty of time for parking, walking there, etc.
If you want to really enjoy snorkeling, it may be better to be in a smaller group on a smaller boat.

Really cool boat! Nice Crew!
Ashley_S, Mar 2023
We went on the Molokini Crater and Turtle Town 5 hour trip. We had perfect weather that day, probably the best day they had seen in weeks. It was a bonus to see whales breaching on the way there and back since it was whale season. The captain said the whale watching didn't get any better than what we got to see as a bonus to the snorkeling trip. The water at Molokini was crystal clear, but we only saw a few different types of fish there. Once the kids and hubby got bored of looking at fish, they enjoyed the two slides and the jump-for-joy off the 2nd deck. We then went to turtle town where the current was very strong and was a bit of a workout to swim from the boat to where the turtles were. We only saw one turtle that was hiding down in a hole, so a little disappointing, but that isn't the crews fault as they can't control the wildlife or ocean currents. The Calypso crew and captain were very helpful and efficient. I did not have super high expectations for a boat that fits 150 people, but the crew really did a great job. Overall it was about 2 hours worth of snorkeling, and 3 hours riding around on the boat there and back and watching whales. They had breakfast(muffins, Danishes, fruit), a mid-morning snack(veggies and bread rolls), lunch(pulled pork or turkey sandwich, cole slaw, chips) and alcoholic beverages(mai tais, rum and coke, local beers) on the ride back to dock, and then surprised us with some ice cream bars which the kids loved! The boat was probably the coolest boat option you could book, with the slides and jump deck, and the view from the 3rd deck was pretty awesome. There was a photographer on the boat as well, and we paid ~$100 to get all access for our family of 5's photos. She offers wristbands to wear if you are very interested in her taking your photos and they are great quality for underwater. Thank you Calypso Crew!

Best experience in Maui! We saw turtles, lots of fish and humpback whales with calf’s! The crew was so helpful and friendly, it made the expense of the trip well worth it!

Sounds like an amazing day of snorkeling at Molokini aboard the Calypso!
A whale of a snorkeling trip
Tammy_W, Mar 2023
Although it wasn’t a whale watching trip, we saw the most whales ever - double and triple breaches as well as a mega pod!
Response from Host, Mar 2023
Whale watching aboard the Calypso snorkel tour is a bonus!
Carla_B, Mar 2023
Crew, boat and food were top-notch. Our 2nd time on this same trip in the past 3 years. Snorkeling at Molokini was a little crowded but that is normal for all boats. Highly recommend. Bonus: whale watching!!
Response from Host, Mar 2023
Sounds like a fantastic snorkeling tour with bonus whale watching aboard the Calypso!
Under water beauty
Allen_P, Mar 2023
Snorkeling with family and loving the whales. Wish we could have seen the turtles but the pollution kept us from doing so
Response from Host, Mar 2023
Thank you for your review. Water clarity varies based on current weather conditions. It was likely run off from recent rain or just sand stirred up by waves that made it more difficult to see marine life. We appreciate you joining us aboard the Calypso snorkeling tour.
James_B, Mar 2023
Molokini crater is a amazing place to visit. The Calipso boat is the best snorkeling and whale watching boat I have ever been on. The design of the boat is fantastic. The back of the boat is all stairs to enter and exit the water. Best design ever. The glass bottom is a nice addition. The upper decks offer plenty of room and 360 degree views. The Captain and crew are 5 star. They are there to make your experience the best possible and they achieve that. Food and service was top notch. My wife and I took 2 excursion on the Calipso and would book again and recommend it to everyone. My wife is in a wheelchair and the boat was very comfortable for her needs. Thank you for the great whale sighting, great snorkeling at Molokini crater, saw 2 turtles up close at Turtle Town, and for a great time and memories on a fantastic boat. Best boat in any harbor hands down. Loved it ❤️
Response from Host, Mar 2023

Well Worth It
Jennie_E, Feb 2023
What an awesome day. We were pampered by the crew from the moment we arrived until departing. It was one of the best customer service events I have experienced in awhile. Great snorkeling and turtle viewing. Excellent food and whale watching too. Do not hesitate to book this experience.

We are so happy to hear that you enjoyed your snorkeling tour to Molokini aboard the Calypso!
Calypso tour was fantastic
Thomas_M, Feb 2023
Calypso tour was fantastic! The boat is huge and there was plenty of room on board for everyone. There was an abundance of food all trip long, from eggs, sausage, and fruit in the morning to pulled pork sandwiches, chips, and veggies in the afternoon. They thought of everything, suntan lotion, snorkel gear, and wet suits (for a small fee). You only need to bring a towel and a smile. On the return, they open the bar and serve drinks for $2!!! I highly recommend booking a trip with Calypso!

A towel and a smile! What a great review of the snorkeling tour to Molokini aboard the Calypso. Thank you for joining us.
Perfect trip!
Christine_B, Feb 2023
It was an amazing time for our family of 6. Crew was very attentive and knowledgeable. The captain made sure we had plenty of opportunity to whale watch.
Response from Host, Feb 2023
Great! Thank you so much for joining us aboard the Calypso snorkeling tour.
Super staff!!
DAUN_B, Feb 2023
The staff were all great. It was super windy and there were a few people that couldn't handle the waves. My husband and I were very queasy but no fault of the staff. They were good at recognizing those that weren't feeling well. The snorkeling was ok, not as many fish as we were expecting. not sure if that had to do with the weather or not. We didn't see any turtles at Turtle town.
Response from Host, Feb 2023
Snorkeling at Molokini is so fun aboard the Calypso! Thank you for sharing your experience.
Amazing experience!
Kerri_O, Feb 2023
From boarding to departing the trip went seamless thanks to the fantastic crew! We stopped at turtle town first, where we were the only boat, then off to Molokini. The hour at Molokini was amazing and there were only a couple of other boats… lots of space and amazing views. Whales were everywhere, including humpback calves! The food was good and none of our group went hungry nor thirsty… enjoy the $2 mai tais! Highly recommend this trip!

Ice cream and snorkeling are a great combo! Thank you for joining us aboard the Calypso snorkeling tour.
Sadly Disappointed
ryan_c, Feb 2023
Due to my own error, I missed out tour. With all the travel planning, I mistakenly thought I had booked this Tuesday, and I had booked Monday. I tried contacting, I left a vm, no response. I had also messaged through Viator, no response. I understand it was a total mistake on my part, this must happen here and there. Planning 7 days in Hawaii can be a little stressful and overwhelming. It would have been nice had someone been kind enough to answer, reply or respond.
Response from Host, Feb 2023
We are sorry to hear that you missed the boat! Please try us next time, we would love to show you how amazing the snorkeling tour aboard the Calypso is. If you'd like to chat with customer service, the number is 1-808-661-3333

Our staff and captain were a joy as was The whale watching. As for the snorkeling, not much to see these days.
Response from Host, Feb 2023
PURE JOY! Thank you for joining us aboard the Calypso snorkeling tour from Lahaina.
Stephanie_S, Feb 2023
The Calypso crew was amazing! We had a wonderful time and the food was yummy! We had a windy day so we didn't get to spend as much time at the crater, but turtle town was calm and worth the trip:-)
Response from Host, Feb 2023
Turtle town on the Molokini snorkeling trip is always the best! Thank you for the great review, we are glad you enjoyed your time aboard the Calypso.
