About Hikiau Falls
Hikiau Falls is a peaceful, picture-postcard waterfall on Hawaiʻi Island near Waipio Valley, set amid lush tropical vegetation and offering a quieter alternative to some of the island’s busier sights. The falls and surrounding lands are within the State Department of Land State Resource Management Area (SRMA) and are managed by the State Department of Land (SDOL), so visitors should be aware they are on state-managed property and exercise Leave No Trace principles. Reaching the falls rewards hikers with a serene, secluded setting framed by verdant forest and valley views. The approach is an out-and-back hike of moderate difficulty (see trail details below); because the route can traverse steep descents and rugged valley terrain, plan your visit with adequate time, footwear, and local condition checks — consider a local guide if you’re unfamiliar with Waipio Valley approaches.
The Setting
Hikiau Falls sits at 210 feet within State Department of Land State Resource Management Area, fed by the Manowaiopae Stream, in the coastal lowlands of Hawaii.
