At the trail’s end is the old Civilian Conservation Corps camp and a three-way junction, the beginning point for both the Plum Trail and the Boundary Trail. Several plum and other fruit trees can be found in this old camp area.

    The Polipoli, Redwood, Plum and Haleakala Ridge Trails form a loop trail worth hiking (3.5 miles).

    There are many other trails in the area, part of an extensive system administered by the State’s Trail and Access system, Nā Ala Hele.

    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. This becomes Polipoli Access Road at 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.
