Where the Hana Highway Breathes: Chasing Waterfalls at Puaʻa Kaʻa State Wayside Park
A compact rainforest pause on the Hana Highway—short walks, twin falls, and a swimming hole that feels like a secret.
You’re rolling east on the Hana Highway, the windshield framing a living watercolor of palms, vine-tangled gulches and highway shoulders bright with ginger and hibiscus. The road slows, then narrows—there’s no traffic light, just a handful of cars and the split-second decision to pull over. From the shoulder you can hear it before you see it: a high, steady rush of water, a small but insistent voice calling from the forest. That sound is Puaʻa Kaʻa, a wayside that feels less like a roadside stop and more like a green room that keeps the Hana-side rainforest on stage.
Trail Wisdom
Go early
Visit in the morning for soft light, fewer crowds and easier parking.
Grip the trail
The paths are short but muddy—wear shoes with tread and take trekking poles if balance is an issue.
Respect the water
Pools have strong currents after rain; don’t overreach and avoid swimming alone.
Support local vendors
Pick up banana bread or fruit from roadside stands to support Hana-area families.
