Kayak Adventures

The signature tour—the Secret Falls Kayak & Hike—glides two miles upstream past taro patches and vine-draped cliffs. Boats beach on a sandy bank, and a mellow rainforest trail leads another mile to 100-foot Uluwehi Falls, where mist cools the air and zebra doves flit through the canopy. Guides tote lunch in dry bags, point out wild ginger and lilikoi, and share the stories behind ancient rock terraces hidden in the undergrowth. Paddling back with the current, you understand why this river once served as a royal highway for Hawaiian chiefs.

Those who prefer extra river time can choose a coastal combo that drifts toward Kamokila Village and the fern-lined pools of Opaekaa Stream, while families often book the gentle Afternoon Leisure Paddle timed for softer light and fewer boats. Each experience includes double or single kayaks, Coast Guard–approved PFDs, dry bags and lightweight paddles, with group sizes capped at about a dozen guests so landings stay organized and photo stops never feel rushed. It is an easy fit for travelers building a full roster of kayaking and other outdoor tours on the east side.

Arrive thirty minutes early to sign waivers, stash non-waterproof gear and apply reef-safe sunscreen. Closed-toe water shoes are smart for the forest path, and a quick-dry shirt earns its keep once the tropical sun breaks over the valley rim. Drinking water is provided, and a shaded picnic area offers a place to wait while guides load the trailer. Tours wrap by mid-afternoon, leaving time to linger at nearby Wailua River State Park or join later island-sightseeing tours along the Coconut Coast. Kayak Adventures combines easy paddling, rainforest scenery and thoughtful guiding into a river-and-waterfall experience that feels refreshingly personal.
