Here’s a trail that’s pretty, easy, and low-elevation, meaning that there’s no excuse not to hike it. The 33-mile Salmon River is one of the very few protected as a National Wild and Scenic River for its entire length—from its headwaters on Mount Hood [1] to its confluence with the Sandy River near Brightwood.
This trail, which runs 14 miles in the Salmon-Huckleberry Wilderness Area but is most often hiked in much smaller chunks, runs right alongside the river; hikers can expect to see wildflowers, old-growth Douglas firs, and a number of campgrounds. In fall, enjoy red and gold maples; year-round, giant cedars and firs dominate.
Access is easy, especially to the lower portion of the trail. From Sandy, follow U.S. 26 east for 17.9 miles and turn right (south) onto the Salmon River Road. Follow this road 5 miles to the trailhead.
