Route: Trail starts above Polipoli Springs State Park on the Skyline switchback at 6,500` elevation and works down the crest of the southwest rift of Haleakala to the Plum Trail junction at the lower forest reserve boundary at 5,600` elevation. Spectacular views extend in all directions. The trail passes alternatively through rough cinders, native scrub brush, grassy swales and a planted forest of pines, eucalyptus and other tree species. The trail joins the end of the Polipoli Trail leading back to the park 0.3 mile from the top. The trail joins the Plum 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 Haleakala Ridge, Polipoli, Redwood and Plum Trails form a loop worth hiking (5.3 miles).
