    Park Name Polipoli Spring State Recreation Area

    Route

    Trail begins at the old Civilian Conservation Corps 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.

    The Plum, Redwood, Haleakala Ridge and Polipoli 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.
