Big Island: Kealakekua Bay Snorkeling by Zodiac & Sea Caves

Summary

Snorkel Kealakekua Bay’s reefs, explore lava tubes and sea caves by Zodiac, snack on the boat and spot dolphins along rugged Big Island coast

You’ll skim across Kona’s waves by Zodiac with a local guide, snorkel among tropical fish in Kealakekua Bay’s crystal waters, snack on sandwiches while watching for dolphins, and slip into secret sea caves along volcanic cliffs. Expect laughter, salt spray, and moments of total quiet you’ll remember long after you’ve dried off.

What’s the experience like?

The first thing I remember is how the Zodiac raft felt under my feet — not quite solid, but not wobbly either. We’d just zipped out from Kona, wind tangling my hair and that salty spray hitting my face (I didn’t mind). Our guide, Kaleo, had this easy way of pointing out things I’d never have noticed: a flash of spinner dolphins off the bow, a line of black lava cliffs that looked almost soft in the early sun. He told us stories about Captain Cook and why Kealakekua Bay means “pathway of the gods” — his voice got quieter for that part. Sometimes you could smell sunscreen and ocean at once.

I’m not a strong swimmer so I was nervous about snorkeling here — but honestly? The water was so clear it felt like flying. Fish everywhere: yellow ones darting around coral heads, blue ones I couldn’t name. Someone handed me a turkey sandwich after (vegan option too), and I swear it tasted better than any picnic lunch should when you’re still dripping wet. There was this moment when we drifted near the Captain Cook monument and everything just went quiet except for the slap of water against the raft. That stuck with me.

We hugged the coastline on the way back, slipping into these wild sea caves where light bounced off wet stone in weird ways. Kaleo joked about pirates hiding treasure there — maybe he tells everyone that story but it made me laugh anyway. If you’re thinking about a day trip to Kealakekua Bay from Kona, don’t expect it to be perfectly smooth (the raft bounces more than you’d think) but that’s part of what makes it real. Oh — bring your own water bottle; they’re serious about no plastic bottles now.
