Wailua River State Park

Wailua River State Park lies in Kauaʻi’s eastern river valley, where the island’s only navigable river runs through tropical greenery. You can paddle or take a boat along the water, stop at scenic overlooks, and visit waterfalls including ‘Opaekaʻa Falls and Wailua Falls. Kayak trips can also lead to a hike to Secret Falls, with a waterfall-fed pool at the end. The park combines outdoor activities with historic and sacred sites, so plan time for both the river and the places on shore.

Explore the river by boat or kayak

The Wailua River is the park’s main route through a green valley. It is Hawaiʻi’s only navigable inland waterway, and kayaking is a popular way to see the scenery from the water. Boat tours are another option for taking in the river at a slower pace.

Some kayak outings combine a paddle upstream with a walk to Secret Falls. The waterfall lies at the end of a trail and flows into a pool where people can swim. Conditions and access can change, so check current information before setting out.

Waterfalls and cultural sites

You can reach some viewpoints and trailheads by road, including stops for ‘Opaekaʻa Falls and Wailua Falls. These roadside views are an option if you have limited time or would rather not take a long walk. The park also includes the Wailua Complex of Heiau, a historic and sacred area associated with places of worship, refuge and royalty.

Treat the cultural sites with care and follow any posted guidance. Park attractions and access information can change, so check the official state park website before your visit.
