About Nanaue Falls

Nanaue Falls is a tucked-away cascade on the Big Island of Hawaii, set among the island’s lush, tropical rainforest. The falls drop along a small stream that threads through dense vegetation, offering a peaceful, secluded spot for hikers who enjoy verdant scenery and the sound of falling water. The site lies within the Kohala Forest Reserve and is managed by SDNR, with an SCA designation that underscores the area’s conservation value—respecting trail etiquette here helps protect the fragile habitat. The hike to the falls is short but rewarding: the route is an out-and-back roughly 1.0 mile in length with about 200 feet of elevation gain, rated moderate. Because the access path is not formally maintained and runs through rainforest terrain, expect muddy or slippery sections after rain and narrow single-track through heavy understory. It’s a great quick hike for those looking to pair a short walk with a quiet waterfall visit—come prepared with sturdy footwear, water, and leave-no-trace habits.

The Setting

Nanaue Falls sits at 1,263 feet within Kohala Forest Reserve, fed by the Alakahi Stream, in the foothills of Hawaii.

Trail & Hike Details

The Approach

The moderate 1.0-mile out-and-back trail gains 200 feet of elevation on the way to the falls.

Trail Description

Trail type: out-and-back; length: 1.0 miles; elevation gain: ~200 feet; difficulty: moderate. The route follows an unmaintained, natural-surface footpath through dense rainforest within the Kohala Forest Reserve (managed by SDNR, SCA). Expect uneven footing, exposed roots and rocks, and sections that become muddy and slippery after rain; grade varies with short steeper pitches but no formal USFS trail class/number is available. Signage and infrastructure are minimal—hikers should wear sturdy shoes, watch footing, and be prepared for a rustic trail experience.

What to Expect

Visitors can expect a tranquil waterfall surrounded by lush greenery. The area is typically quiet and less crowded than other waterfalls on the island. However, access may involve navigating unmarked trails or private property, so visitors should proceed respectfully and cautiously.

Accessibility

The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.
