Kuliʻouʻou Ridge Trail Hiking Guide
Kuliʻouʻou Ridge is the classic east Honolulu climb to the crest of the Koʻolau Range: switchbacks through shady planted forest, then a long, open ridge of steps to a summit that looks straight down on Waimānalo. It is a free state trail that starts in a quiet residential valley. Count on a few hours and real effort.
Distance and Climb
Nā Ala Hele lists the ridge trail at 2.1 miles and 1,605 feet of gain from its junction with the valley trail. AllTrails maps the full outing from the street at 4.8 miles round trip with about 1,740 feet of climbing. The first part switchbacks up the valley wall; the second half follows the ridge crest to the summit. Most of the work comes in the upper third.
From Kalaʻau Place to the Summit
Walk past the cable gate at the end of Kalaʻau Place onto a Board of Water Supply road, sign in at the hunter and hiker check-in mailbox, and follow the Kuliʻouʻou Valley Trail about 0.2 mile to a signed junction with a boot-cleaning station. Turn sharp right up the switchbacks through Formosa koa and logwood, which Civilian Conservation Corps crews planted in 1934 and 1935 to slow erosion. On the ridge you pass ironwood, Cook pines and two covered picnic tables before the climb steepens on plastic steps.
Mud, Steps and the Summit Edge
Above the picnic shelter the state says the trail is maintained only occasionally and can be rough and eroded, and the plastic steps get slick when the ridge is wet. The summit is an eroded knob at the edge of the windward cliffs, with a sheer drop. In December 2025 two visitors had to be rescued over two days after one slid about 30 feet from the top. Stay back from the edge, and skip the summit push when clouds and rain are sitting on the crest.
Hunters, Bikes and Dogs
The trail crosses a public hunting area and is open to mountain bikes. Nā Ala Hele asks hikers to wear bright clothing and stay on the trail, since hunters may be working off it. Leashed dogs are allowed; hunting dogs may be off leash during a hunt. The upper ridge opens into native uluhe, ʻōhiʻa, koa and lama forest with views nearly all the way around the island; brush seeds off your boots at the stations to keep weeds out.
Parking in the Neighborhood
There is no lot. Park on the street along Kalaʻau Place, but not in the posted no-parking area at the end of the cul-de-sac, and drive slowly on Kuliʻouʻou and Elelupe Roads and watch for children. This trailhead sits in a residential neighborhood, and the state asks hikers to stay quiet there and to park legally. There is no fee or permit.
