Big Island: Kealakekua Bay Snorkeling & Zodiac Caves Tour

Summary

Snorkel crystal reefs see dolphins and hear legends along Kona coast

You’ll bounce along Kona’s rugged shoreline by Zodiac boat with a local guide, then snorkel Kealakekua Bay’s vibrant reefs—where tropical fish swirl beneath you. Taste fresh fruit after swimming and hear stories of Captain Cook at his monument. Expect laughter, salty air, and moments that linger quietly after you’re back on shore.

What’s the experience like?

I almost missed the turn into Honokohau Harbor—my phone lost signal right when I needed it most. The office was easy enough to spot once I got my bearings, though, with a sleepy golden retriever sprawled out by the door (I gave him a scratch behind the ears; he looked like he’d seen a lot of travelers come and go). Inside felt more like someone’s living room than a tour check-in. Air conditioning, a few families chatting quietly, and the faint smell of reef-safe sunscreen in the air. I grabbed an extra cookie from the snack table before we headed out—nerves, maybe.

The Zodiac ride itself was nothing like those big tourist boats you see in brochures. It was low to the water, bouncy in that way that makes you laugh or grab onto your neighbor (I did both). Our captain, Kaleo, kept pointing out things I’d never have noticed: a pod of spinner dolphins gliding just off our bow, lava tubes carved into black cliffs. He told us stories about old Hawaii—how this coastline shaped the people here—and even stopped so we could take photos with Mauna Loa looming behind us. Someone asked about Captain Cook and Kaleo just grinned: “You’ll see.”

I’ll admit, I was nervous slipping into Kealakekua Bay—the water looked impossibly clear but also deep enough to swallow me whole. But once my face hit the water? It was like being inside an aquarium: coral gardens swaying under me, fish darting everywhere (I recognized maybe three types; our guide knew them all by name). The sun flickered through the surface and everything went quiet except for my own breath in the snorkel. When I popped up, someone handed me pineapple slices and cold water—tasted sweeter after swimming.

We drifted near the Captain Cook Monument while Kaleo shared what really happened here—not just what’s on plaques. On the ride back along the Kona coast, he pointed out places only locals know for poke or malasadas (I wrote one down but lost it somewhere between wet towels). The wind tangled my hair and there was salt on my lips. I still think about that feeling—sun-tired but happy—long after we pulled back into harbor.
