4 hrs
Snacks, drinks, snorkel gear
Snorkel Kealakekua Bay's reef near the Captain Cook Monument, where endemic fish live only in Hawaii. Travel aboard a fast, wet boat with limited shade and storage.
Our adventure at Honokohau Marina where we gear up to snorkel the waters off the Kona Coast. We head to the pristine marine sanctuary of Kealakekua Bay, known as one of the best snorkeling spots in the world and home to the famous Captain Cook Monument.
As we cruise along the stunning Kona coastline, we'll keep an eye out for Hawaiian spinner dolphins in their natural habitat, retreating to secluded coves after a night of hunting. Our journey into the open sea might even reward us with sightings of bottlenose dolphins, pilot whales, and spotted dolphins. And who knows? We might even spot a whale shark! During the winter months, we often see Humpback whales and their calves, which might treat us to some spectacular spouting and breaching.
When we reach Kealakekua Bay, you’ll have the chance to snorkel in clear, fish-filled waters, view vibrant coral reefs, and explore the marine life around the easily accessible Captain Cook Monument. We’ll provide snacks and drinks while sharing the intriguing stories of Captain Cook’s adventures. You’ll have plenty of time to enjoy the water and the underwater sights.
On our way back, we’ll take in the dramatic cliffs and explore ancient coastal sea caves formed by lava flows, all while learning about Hawaiian history and myths. Join us for this memorable day of exploration and fun on our Captain Cook snorkeling tour.

If manta ray encounters are on your bucket list, this is the operation to book. Reviewers consistently rave about getting up close with mantas, spinner dolphins, sea turtles, and even the occasional sandbar shark. The wildlife sightings sound genuinely spectacular, not just lucky one-offs. The crew gets called out by name constantly, with guides like Tori, Adam, Ty, Amy, and Shari earning praise for being knowledgeable, enthusiastic, and great at keeping groups engaged and safe. That personal touch seems to elevate the experience well beyond a standard boat tour. With nearly perfect ratings across thousands of reviews and zero consistent complaints to speak of, the pattern here is hard to ignore. The manta ray night snorkel in particular gets described as a trip highlight by almost everyone who does it. If you're on the Big Island and on the fence, the overwhelming consensus is pretty clear: just go.
Awesome tour! We saw several rays and the tour guide and captain were great!
