McKenzie River Trail, Eugene, Ore.

The McKenzie River Trail stretches around 25 miles through the majestic forests of the Cascade Mountains. It winds through spectacular waterfalls, lava fields and old-growth trees. Runners can lengthen or shorten their sprints by taking advantage of a shuttle service. The trail is also a favorite with mountain bikers, who have dubbed it the top trail in the nation.

For serious runners, McKenzie River Trail is also the location of the famous 50-mile race, which starts and finishes at the McKenzie River Ranger Station.
