About Paaiki Falls
Paaiki Falls is a picturesque cascade on the Big Island of Hawai‘i, part of the Wailuku River system and set amid lush, tropical vegetation. The falls and their fern-lined banks make for a rewarding short outing for hikers and photographers looking to experience a quieter pocket of the island’s interior. The waterfall sits within the Pu'u Ka Pele Forest Reserve, a State-designated SCA managed by SDNR, so visitors should be mindful of reserve rules and signage while enjoying the area. Expect a natural, undeveloped setting and plan to practice Leave No Trace principles when visiting this scenic spot.
The Setting
Paaiki Falls sits at 1,207 feet within Pu'u Ka Pele Forest Reserve, fed by the Kawaikoi Stream, in the foothills 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
The route to Paaiki Falls is a moderate 2.4-mile out-and-back with roughly 350 feet of elevation gain. Trail records list the length, elevation gain and difficulty but do not publish an official surface, grade, or trail class; hikers should therefore anticipate natural dirt tread, uneven footing and moderate climbs in places. The land unit is managed by SDNR (Pu'u Ka Pele Forest Reserve, SCA), so stay on marked routes, obey posted regulations, and bring sturdy footwear and basic navigation supplies.
What to Expect
Visitors can expect a serene and lush environment typical of Hawaii's waterfalls. However, access to Paaiki Falls may be challenging or restricted, and the falls are not as easily accessible as other nearby attractions like Rainbow Falls.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.
