The "Dikes" trails on the east side of Lebanon, Oregon roll along the western bank of the South Santiam River. The trails have existed for many generations, and offer approximately 2.5 miles of easy - moderate singletrack riding. There are two parallel trails: 1 "Upper" trail running along the tallest dike, and one "Lower" trail running about halfway between the upper trail and the river, with many connector trails between them and the river. Although this trail system may not seem worth an hour+ drive, they have proven to be a fairly popular trail system for hikers and bikers in and around Lebanon for many years.
Trailheads at either end of the loop (Gill's Landing to the north, or near Riverview School to the south). Additional trailhead at the east end of Milton Street, but if you access the trails from there, be sure to turn immediately to the right (over the short metal fence) just beyond the gate, as the mill property beyond is posted No Trespassing (and the rent-a-cop, who obviously needs to ride these trails, will likely pull up in his Ford Taurus Security Car, set his donut box aside, and try toâ¦Â uhhh, throw his weight around).
