The massive Mt. Pisgah Arboretum, located along the Willamette River just a few miles from downtown Eugene, is another great close-to-town trail running option. With 209 acres brimming with paths, there are numerous running options here, many of which provide a challenging climb up to the summit of Pisgah. However, the paths are generally well groomed and free of the hazardous roots and rocks frequenting most trail runs. One popular option is to take Trail 5, Trail 4, and Trail 17 for a flat 8 mile loop around the park. Be prepared to pay a $4 fee to park at the main lot. Annual passes are also available.
