Route: Trail begins at the old Civilian Conservation Corp. area and climbs gradually across the mountain through a planted forest of ash, redwood, sugi, and other species until it joins the Haleakala Ridge Trail. Numerous plum trees bearing fruit during the summer can be found along the trail. Wear bright clothing. Be aware that you may encounter hunters who are hunting off the trail. Stay on trail.

Directions: From Kahului, take Highway 37 past Pukalani to the second junction of Highway 377. Turn left on 377 for about 0.3 mile, then right on Waipoli Road. The road travels through the first cattle guard and climbs up the mountain through a long series of switchbacks until it enters the forest at 6,400` elevation, where the pavement ends.

The Plum, Redwood, Haleakala Ridge and Polipoli Trails form a loop trail worth hiking (5.3 miles).
