East of Eugene and west of Sisters in the Willamette National Forest, the McKenzie River Trail (#3507) is a 26.5 mile long mountain bike mountain bike trek through volcanic lands along a wild whitewater river. The route runs through thick old growth cedars past waterfalls and hot springs. It is pretty much a rolling forested route with occasional river views. From the lower trailhead to the upper trailhead, there is a 1,700 feet vertical difference, but with all the rolling hills along the route, you can expect a lot more climbing.
The McKenzie River Trail runs along SR126 from Clear Lake near SR 20, down to the town of McKenzie Bridge, approximately 50 miles east of Eugene. The upper trailhead is located 1.8 miles south of US20 on SR126 just south of FS2676.
There is a one-way shuttle available from Pauls Bicycles (541) 344-4150.
Overall, McKenzie River National Recreation Trail is the 2nd most popular mountain bike trail of all 55 mountain biking rides in Oregon.
