About Waimanu Falls
Waimanu Falls plunges in two dramatic tiers into a secluded pool tucked deep in Waimanu Valley on Molokaʻi. Nestled within the Molokaʻi Forest Reserve and managed by the State of Hawaiʻi Department of Land and Natural Resources (SDNR), the falls are framed by lush tropical vegetation and steep valley walls that reward hikers with a real sense of remoteness and wild beauty. Visitors come for the quiet cascade, the verdant gorge, and the feeling of stepping into an untouched corner of the island. The most common approach is via the historic Muliwai Trail, which traverses coastal ridgelines and rainforest before dropping into the valley floor. Although access is limited and the route requires steady footing, the payoff is a pristine swimming hole beneath the falls and striking views back up the valley. Because the site sits on SDNR-managed lands in the Molokaʻi Forest Reserve, visitors should respect local rules and leave no trace to help preserve this special area.
Trail Description
Muliwai Trail to Waimanu Falls is an out-and-back route of roughly 2.4 miles with about 350 feet of elevation gain and a moderate difficulty rating. The trail moves from exposed coastal ridges into dense tropical forest and includes some steep sections and stream crossings that require careful footing. Expect uneven dirt and root-covered tread rather than developed surfacing; the trail is rugged in places and best suited to hikers prepared for a natural backcountry path. Signage and formal infrastructure are minimal on SDNR-managed lands, so carry essentials (water, rain gear, sturdy shoes) and plan for limited cell service. The route’s moderate overall grade belies occasional short, steeper pitches—take your time on descents into the valley and allow extra time for the return climb.
