Mahana Ridge Trail

Mahana Ridge Trail climbs inland from D.T. Fleming Beach through old resort and ranch land toward the forested slopes above Kapalua. This entry covers a four-mile out-and-back to the reservoir, with about 750 feet of climbing and roughly two to three hours on foot. It is a moderate half-day hike if you are comfortable on a narrow, sometimes overgrown trail and one steep stepped climb. The coast is close at the start, then the route rises through a gulch and into greener, quieter country. The reservoir gives you a clear place to turn around without committing to the unsettled upper route.

Park at D.T. Fleming Beach Park, then walk back along the access road toward the small green preschool near the trail entrance. The route starts as a narrow dirt track through tall kiawe and grass, passes beneath Honoapiʻilani Highway, and climbs beside golf-course support buildings. At about 0.8 mile, it reaches a paved access road. Follow it left for roughly 150 yards and look for the trail continuing on the right. This short link is easy to miss, so pay attention where the footpath meets pavement.

The trail drops into a gulch, then climbs steeply up the other side on stone steps set into the slope. This is the hardest part of the reservoir outing: it is short, but the grade is abrupt and the steps can be uneven. Near the top, a small break in the trees opens toward Molokaʻi. For a photo, keep a little of the ridge vegetation or trail in the foreground so the island has a sense of distance. After the climb, the path eases into a quieter stretch beneath a mix of trees.

The reservoir is about two miles from the beach entrance and makes the practical turnaround for this route. Stop here, then retrace your steps for a four-mile round trip. The full named ridge continues beyond the water toward Maunalei Arboretum, but published distances to the upper end vary widely, and visitors have reported a locked gate. There is no shuttle back down. Treat the reservoir as the end of this mapped hike; do not plan on a through-route or a vehicle exit from the upper neighborhood unless access has been confirmed before you start.

The lower trail crosses land once used by Honolua Ranch for coffee and pineapple. The higher slopes carry a patchwork of native and introduced trees rather than a single uniform forest. On the longer continuation above the reservoir, route descriptions point out pineapple left from plantation use, Cook Island pines, and planted Japanese sugi trees. Maunalei Arboretum was established by plantation manager D.T. Fleming about 80 years ago, with trees and plants gathered from around the world alongside native Hawaiian species. Those groves are beyond the reservoir turnaround, but they explain why this ridge has a different feel from the open coastal walks nearby.

D.T. Fleming Beach Park has restrooms and water near the starting access; no food stop is documented along the hike, so bring what you need from the coast. The route is for daylight hours, and dogs are prohibited. The lower tread is often overgrown, and the surfaced connectors and junctions can make the line hard to follow. Mud and slick footing are recurring problems after rain, especially on the gulch descent and climb. Give yourself time to return the same way rather than racing the daylight.
