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. Explore sea caves, coves along the rugged Kona coastline—places larger boats can’t access. 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. Come explore the Big Island coast with us—the local way, without the crowds.

2.00Boat ride to the snorkel location is uncomfortable. Going very fast and hitting the swells made for a long and bumpy ride. Kids might enjoy the ride but anyone with a bad back or an older adult won’t. There is no cover for shade. Because you can’t snorkel near the rocks, there’s few fish to see. Food and drink consisted of a few pieces of pineapple and a small bottle of water (8 oz ). There was no mention of dolphins although that was advertised. ( I realize there’s no guarantee for seeing them). The crew was friendly and pointed out some historical sights on the boat ride back. Overall, not worth it.
Great Experience

5.00Chip and Adam were highly entertaining and quite knowledgeable as well. The trip to the bay was quick and the reef was amazing! Just be aware that check in and launch are two different locations (as stated on the ticket), and some folks weren’t quite timely in arriving, but it didn’t impact our time out in the water. Would highly recommend!
