WHAT A GREAT EXPERIENCE!

"What a great experience! We'd met Capt. Lorin before when she crewed on another adventure, so we knew we were in great hands. She and her (all female) crew on Adventure-X were professional and informative yet fun too! We were a group of 9, & all of us live here, so we're on boats a lot and this was one of the best. The snorkelers on board saw honu (turtles), lots of fish & we all saw some frisky flying fish too. The humpback whales put on a fantastic show near the end - it was a perfect '3 hour tour.' Oh - they provided snacks, fresh fruit & drinks too. Highly recommended!"

YOU'RE IN GREAT HANDS

"We had an amazing experience on our manta ray tour! The entire crew (Cassandra, Riley, and Garrett) were professional, friendly, and made us feel comfortable from start to finish. A special shoutout to Captain Garrett, who truly made the trip exceptional. He was incredibly knowledgeable, patient, and took the time to answer everyone's questions throughout the tour. Whether people were curious about the manta rays, the boat, or the local area, Garrett never seemed rushed and made sure everyone felt included and informed. You can tell he genuinely enjoys what he does and cares about giving guests a great experience. His calm demeanor and attention to everyone on board helped create a fun and welcoming atmosphere. The manta ray encounter itself was unforgettable, and seeing these incredible animals up close was absolutely breathtaking. If you're considering a manta ray tour, I highly recommend this company, and if you get Captain Garrett, you're in great hands!"

HIGHLY RECOMMEND

"What an incredible way to spend our early morning with our entire family!! Eight of us had our own private tour. So many whales, including one whale who repeatedly slapped its tail on the water. Becca and Loraine were amazing guides sharing all the fun whale facts. We also had the chance to hear the whales singing. Magical. The snacks and drinks were a great touch, including delicious pineapple boats. Highly recommend!!"
