Trail shared by Megan W

The mellow Sage Trail circles about 2/3 of Boulder Valley Ranch and treats users to good views.

Runner Notes

Generally good surface, but bike and horse traffic can cause ruts especially after rain. There are usually smoother parts near the edges. This is a good trail for winter running, the area melts and dries out quickly.


Expect to share this popular trail with mountain bikers, equestrians and off-leash dogs. Although the Sage trail can be done on its own and in either direction, it makes a satisfying and logical loop (Boulder Valley Ranch Loop) when combined with the Eagle Trail.

The Boulder Valley Ranch Trailhead and parking area falls mid-way along the Sage Trail. This description begins on the southern end of the Sage Trail where the Eagle Trail climbs steeply up a mesa. The Sage Trail starts by heading west under tall cottonwoods and along the farmer's irrigation ditch (built in 1862). This is the only shade in the whole area, so enjoy it! The trail is easy going, flat and wide with a smooth dirt surface.

After crossing through the Boulder Valley Ranch Trailhead parking area, open a gate and head right (northeast) to continue on the Sage Trail. Views of the Boulder County foothills open up. The trail meanders through a few shallow ravines and next to a private working ranch. This is a chance to see barns, stables and friendly horses up close. Climb up a short incline and views of the flatirons and a small pond are revealed. After the junction with the North Rim Trail, continue along through open, grassy pastures inhabited by prairie dogs. In the distance to the east you'll see Boulder Reservoir and Sixmile Reservoir. The Sage Trail ends at a gate and junction with the Eagle Trail.
