About Aimoo Falls

Aimoo Falls is a tucked-away cascade set within the Kohala Forest Reserve on Hawaiʻi Island, managed by the State Department of Land and Natural Resources (SDNR). Nestled in a lush tropical setting, the falls are a quieter alternative to better-known island attractions, offering a peaceful spot to enjoy forest shade and the sound of falling water. Specific measurements for the falls’ height are not well documented, which adds to its off‑the‑beaten‑path appeal for explorers who prefer less-trafficked destinations. Access to Aimoo Falls is via SDNR lands designated as an SCA and overseen by the department, so visitors should respect local rules and any seasonal closures. The approach is an engaging, moderately paced hike through native vegetation; because the route is managed by SDNR rather than the U.S. Forest Service, there is no USFS trail number for this site. If you like quiet forest hikes and a bit of discovery, Aimoo Falls rewards visitors with a serene Hawaiian waterfall experience.

The Setting

Aimoo Falls sits at 1,959 feet within Kohala Forest Reserve, fed by the Alakahi Stream, in the hills of Hawaii.

Trail Description

Official surface, grade, and USFS trail class data are not available for this SDNR-managed route in the Kohala Forest Reserve.

Because detailed surface and class information aren’t published, come prepared with sturdy footwear, water, and basic navigation tools, and check with SDNR for any access guidelines before heading out.
