What To Expect
Skip the crowded tourist boats with 30 to 80 people and join our small-group snorkel tour aboard a Navy-style Zodiac RIB speed boat. We’ll take you on a fast, scenic ride to Kealakekua Bay, home of the Captain Cook Monument and some of the clearest, most vibrant coral reef snorkeling on the Big Island.

You may even spot dolphins, whales, or other marine wildlife along the way (wildlife sightings are NOT guaranteed). Your tour includes snorkel mask & snorkel, pineapple and water. Wetsuits and lifejackets are available for rent at check-in if desired. Our crew will guide you every step of the way, ensuring comfort, safety, and a memorable experience. ⏱️ Tour duration is approximately 2–3 hours (2.5 hours on average), but can vary depending on ocean conditions, snorkeling time, and wildlife activity.

5.00This was an incredible experience and the tour operator and cree were great. We loved the location and extra bits of information shared. Biggest plus was their exceptional customer service. Our flight to HI was delayed a full day due to the Alaska Airlines cyber attacked that occurred in July 2025 and we needed to reschedule our tour at the last minute. No problem nor issues and no extra fees either. This was a huge positive impression for us during those stressful 24 hours.
Great time!

5.00It’s a smaller boat, about 18 people. It was a lot of fun, picking up speed out in the open ocean. We saw a tiger shark and some dolphin. When we got to Captain Cook we had an amazing time snorkeling, lots of beautiful fish. My daughters (10 & 14) thought 60 mins snorkeling was too long, but my husband and I enjoyed it. The boat ride back was fun, we stopped at different spots along coast and learned about some Hawaii history.
It was our first time...

5.00It was our first time snorkeling. Captain Shaka and Bradley were amazing. They asked us to wait after everyone was in water to go over the instructions. The speed boat ride was thrilling and the captain made it extra fun with all the twist and turns. We saw some dolphins. On our way back, they showed us lava tubes and caves.
