Review: October 25th, 2019
The John Day River is the longest wild river in the Northwest. It is over 252 miles long and it begins at an elevation of 8,400 feet. For millions of years as the earth rose the river cut through the basalt to form tall cliffs and a narrow valley. The base of the river is the Grand Ronde basalt flows which spilled over the land in a sea of molten lava about 16 million years ago.

From the day use area head a bit towards the river towards the right. Stop in at the visitor’s center for information about the park. Cottonwood Canyon State Park opened September 25th 2013. The state park is 7,800 acres and is an old cattle ranch that was sold to Oregon when the Murtha family decided the place should be shared with the public.

Turn left onto the Willow Flats Trail and follow the paved trail along the river for about 0.7 mile to the Pinnacles Trail.

The Pinnacles Trail, leaving from the end of the campground, is open to bikers and hikers. There are some lovely vistas near the river, looking downstream. Pass by an overhanging basalt cliff where there are nests of cliff swallows with swarms of birds gathering insects to feed their young. Hike downriver about 1.5 miles through the wide canyon and you come to the junction for the Lower Walnut Trail. The Walnut Trail runs close to the John Day River and winds through mostly sagebrush to rejoin the main trail in about 0.5 mile. You can take a side trip into the riverbed during low-water for nice views upstream. From the junction of the Walnut Trail hunting is allowed so wear some bright color during the hunting season.

Continuing downstream you’ll round a large bend in the river as the trail goes around Gooseneck Peninsula. The peninsula is about ¾ mile across so you might not notice you are making a giant U-turn.

Eventually the trail goes along a barb-wire fence then comes to a gate. Past the gate the river is eating away the bank so there is no easy river access here. This is really the farthest you can go on the trail.

Enjoy the photos!!
