Departing from Kawaihae Harbor, we venture directly into the renowned humpback whale nursery grounds along the Kohala Coast—an area where mothers nurture their newborn calves and unforgettable encounters are possible. This coastline offers some of the highest whale-sighting opportunities in Hawaiʻi, giving you the rare chance to witness these majestic giants up close as they rest, bond, and prepare their young for the long journey ahead.
This is one of the Big Island’s most extraordinary experiences—just minutes from the Waikoloa Resort coastline. Slip into the water beneath the glow of specialized lights and watch as graceful, gentle manta rays soar and spiral through the darkness, feeding on clouds of plankton. With an expert guide at your side, you’ll witness this rare natural spectacle in a safe, serene, and truly magical setting.
A beautiful way to experience the west side of the Big Island. Our intimate boat tour allows you to view our magical spinner dolphins from the boat. After, we will visit a snorkel location where we will snorkel with turtles. We are very close to the Hilton, Marriot, Mauna Lani, Fairmont, Hapuna Westin, and Mauna Kea Beach hotel.

"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!"
– Jen Yankee Caulfield · TripAdvisor"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!"
– Haley Erkman · TripAdvisor"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!!"
