This trail is currenlty closed. Much of the Poal Creek Wilderness and Jawbone Flats burned in the Beachie Creek fire during the summer of 2020. It may remain closed for some time.
Opal Pool is located within a beautiful old growth forest in the Opal Creek Wilderness. Some of the trees here have been dated to be over 1,000 years old. The trail can be packed in the summer, with visitors taking advantage of the cold water on a hot day with some of the state’s best swimming holes. Pools below Sawmill Falls, sliding down Slide Falls, and jumping off the 30 foot cliffs into Opal Pool itself are all popular pastimes. The autumn can be a specular time to visit as well, as the leaves change and the flows over the falls increase with the fall rains.
The trail actually begins as the road the Jawbone Flats, a historic town which is now part of a private environmental education center and outdoor museum. Head up the road along the Little North Santiam River, passing over Gold Creek and a series of half bridges built into the cliff face. At about 2 miles, look for the remnants of the old Merten Mill, where various pieces of equipment still lay abandoned.
At about 2.5 miles, the Kopetski Trail reads to the right over a footbridge over the Little North Santiam. This trail then continues up the river on the southern bank as it works its way to Opal Pool. About ½ mile up this trail, watch for a little side trail dropping down to Slide Falls. It’s roughly 1.25 miles from where you crossed the bridge until you reach beautiful Opal Pool.
Opal Pool is situated right below a very narrow chasm and below Opal Pool Falls. The pool can be viewed from many different locations, but the best are located along the bank before you cross the bridge and on the bridge itself. Once you’ve had your fill, continue over the bridge and head to your left, towards Jawbone Flats. There are a number of cool, old mining relics here, but the buildings are occupied private property, so be respectful. Once in town, just follow the gravel road a little over 3 miles back to the trailhead.
Take Highway 22, between Salem and Sisters until you reach the town of Gates, a small community west of Detroit Lake. Take Gates Hill Road north for about 4 miles until you reach the Elkhorn Valley Golf Course and the intersection with the North Fork Road. Make a right onto North Fork Road and follow the windy road for about 11 miles until you reach the trailhead. Be aware that because of significant crowding and vandalism, the Forest Service is turning away vehicles once the parking area is full. So it pays to be early on busy, summer weekends.
