The Experience

We’d barely left the harbor before the water changed color—suddenly this insane blue, almost glassy. I could smell salt and sunscreen (mine, mostly), and our captain, Kaleo, was already pointing out shapes along the cliffs. “That’s where my uncle used to fish,” he said, and it felt like we were getting let in on some family secret. The boat was small enough that you could hear everyone’s laughter over the motor, which is rare. I kept thinking: this is farther than I’ve ever been down the South Kona coast.

The first stop was Kealakekua Bay. It’s famous for a reason—I mean, you put your face in and there are these clouds of yellow tangs everywhere. Our guide handed me a mask that didn’t fog up (bless her) and showed us how to spot the little cleaner wrasses doing their thing on bigger fish. At one point I heard someone shout “dolphins!” but honestly I was too busy following this green sea turtle along the rocks. The sun came out strong right then and everything looked sharper underwater—almost too much color.

After sandwiches (I went with turkey—should’ve tried tuna), we drifted toward Puʻuhonua O Honaunau. There’s something about being close to a place with so much history; Kaleo told us stories about ancient Hawaiians seeking refuge here, his voice kind of quiet over the water. We ducked into a lava tube—cold shadows inside after all that sun—and I remember touching the rock wall just because it felt weirdly smooth for something so old. Last stop was a black sand beach with nobody else around except some nervous crabs skittering away from our toes. That silence hit different after all the boat noise.

I didn’t expect to feel so tired but also kind of lucky by the end—like we’d seen parts of Hawaii most people don’t even know how to look for. Still think about that turtle sometimes.
