About Waiʻilikahi Falls
Waiʻilikahi Falls sits deep in the remote Waimanu Valley on the northeast coast of Hawaiʻi island, a spot long prized for its seclusion and dramatic scenery. The cascade plunges through a lush amphitheater of tropical vegetation, offering a rewarding payoff after the valley’s rugged approach. The falls and surrounding shoreline are part of the Waimanu Estuarine Research Reserve — designated as an SCA and managed by SPR — so visitors should treat the area with extra care to preserve its pristine character. Waimanu Valley itself is one of the island’s most remote valleys and, besides the main Waimanu Stream, contains other noteworthy features such as Waihīlau Falls on a nearby tributary (Wikipedia).
The Setting
Waiʻilikahi Falls sits at 89 feet within Waimanu Estuarine Research Reserve, fed by the Kawainui Stream, in the coastal lowlands of Hawaii.
Trail & Hike Details
The Approach
The moderate 2.4-mile out-and-back trail gains 350 feet of elevation on the way to the falls.
Trail Description
Access to Waiʻilikahi Falls is most commonly via the Muliwai Trail into Waimanu Valley. The official approach is an out-and-back route of about 2.4 miles (one-way details vary) with roughly 350 feet of elevation change; guide difficulty is considered moderate. The hike begins with a steep climb out of Waipiʻo Valley, then traverses rugged terrain and dense forest with multiple stream crossings before descending into the floor of Waimanu Valley. From the valley floor you’ll need to navigate through thick vegetation to reach the base of the falls. Specific USFS trail surface, grade, or class data are not provided here, so expect an unmarked, natural tread and variable footing; good footwear, river-crossing awareness, and preparation for backcountry conditions are recommended.
What to Expect
Swimming is permitted.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.
