ʻOpaekaʻa Falls
The easiest waterfall on Kauaʻi to see.
A roadside lookout up Kuamoʻo Road, with the falls pouring into a green bowl across the valley. Cross the street for the Wailua River overlook, and Poliʻahu Heiau waits just up the hill. Same state park as Wailua Falls, same 2026 rule: non-residents now pay to enter and park.
