Plaza Trail is one of the more rugged and isolated trails you can take on the Mt. Hood National Forest, close to Portland. Even on a summer weekend day, you are not likely to run into more than a few other hikers, if that. You can reach Plaza Trail on the north end by parking in the BLM Wildwood Day Use Area off Hwy 26 near Welches, and hiking 4 miles south on Boulder Ridge Trail #783A
to its end and pick up Plaza Trail. Or you can start Plaza Trail on the south end, off of Abbot Road outside of Estacada off Hwy 224.
In either case, Plaza Trail follows the ridge lines of the Salmon-Huckleberry Wilderness namesake mountains. At the end of Boulder Ridge, Plaza Trail follows the ridgeline of Huckleberry Mountain as it winds across the wilderness towards Salmon Mountain and then a feature called Sheepshead Rock at the south end of the wilderness. The following description assumes you start at the south end and hike north.

Plaza Trail runs through thick second growth forests of Douglas fir, mountain hemlock, silver fir, and noble fir. Vine maple and alder make for fall colors. Undergrowth consists of sword ferns, salal, Oregon grape, and rhododendrons. Blooms are best in June and include bear grass, lupine, penstemon, Indian paintbrush, larkspur and many other wildflowers that are found in the rocky outcroppings along this trail.
