About Waiohiwi Falls
Waiohiwi Falls is a quiet, green sanctuary tucked into Hawaii’s tropical landscape. The fall’s remote setting and dense vegetation create a serene backdrop for photography and reflection, and its lesser-known status means you’re likely to enjoy a peaceful visit away from crowded viewpoints. Because the waterfall sits within a Private Landowner Watershed Protection Area (WPA), the parcel is owned and managed by a private landowner (PVT); visitors should respect posted rules and any access restrictions the property owner may set. The approach to the falls is a modest but rewarding hike: the trail is an out-and-back roughly 2.4 miles long with about 350 feet of elevation gain and is typically rated moderate. The route threads through tropical forest and offers a close-up sense of Hawaii’s native vegetation and streamside scenery, making it a good pick for hikers who want solitude paired with classic island greenery.
The Setting
Waiohiwi Falls sits at 1,985 feet within Private Landowner Watershed Protection Area, fed by the Honopou Stream, in the hills of Hawaii.
