Wailua River State Park incorporates the historical and natural sites on and around the Wailua River in eastern Kauai. Ten story high Secret Falls, can be reached after a one mile hike from the banks of the river.
Note: the photographer previously identified this photo as Ho'olalaea Falls. That appears to have been an error.
