The Hike

This scenic river trail begins at Rainbow Campground, located on the Oak Grove Fork of the Clackamas River. This tributary of the Clackamas River is about 25.0 miles long; it flows into Timothy Lake and then flows out of the reservoir for about 16.0 miles and empties into the Clackamas River at Rainbow Campground. The riverside path twists and turns through immense red cedars surrounded by a shimmering green carpet of sword ferns. These amazing trees thrive in areas with a moist environment and are in demand by lumber mills. Trees that have escaped the logger’s ax can grow to be 200 feet high and 8 to 10 feet in diameter.

As you hike you’ll pass a boggy area at mile 1.4 that is filled with yellow skunk cabbage. This curious plant gives off a skunklike odor that is produced by sap in the flowers and attracts pollinating insects. Native Americans soaked the roots of this plant for many days before eating them. This soaking process helped leech out the calcium oxalate that can cause the throat and tongue to swell and can also cause temporary paralysis of the salivary glands. Flour was also made from the dried roots, and the leaves were used to make water containers and to relieve headaches and fevers.

Additional highlights on this trail include awesome swimming holes and many spectacular viewpoints of the Clackamas River. At mile 4.2 you’ll arrive at Riverside Campground (your turnaround point). After taking a break, retrace the same route back to the trailhead.
