Wailua River State Park

Wailua River State Park stretches across a valley floor with tropical forests and runs along the state's only navigable river. The park contains multiple waterfalls, cave formations, and a complex of ancient stone structures that rise from the forest.

Sacred temples and stone structures in the park served as power centers for Hawaiian chiefs during ancient times. These sites were religious and ceremonial hubs that shaped the region's early history.

The site held deep spiritual importance for ancient Hawaiians who performed royal ceremonies and connected with their traditions here. You can sense this sacred character when walking through the valley.

The park welcomes visitors daily without entrance fees and offers boat tours and kayak rentals at the marina. Come prepared for humid conditions and wet footing on trails, as the tropical environment stays damp year-round.

The park's Fern Grotto is a natural cave where delicate ferns grow upside down from the ceiling in an unusual botanical display. This geological feature creates an otherworldly space that feels entirely removed from the rest of the valley.
