Sage Trail, Boulder
It’s hard to believe you’re only four miles from downtown Boulder on this quiet run through picturesque farmland. The three-mile loop is a nice, quick outing and it can be used to access the Eagle Trail to the Mesa Reservoir for a longer run.
Distance: 3 miles (loop)
Elevation Gain: 200 feet
Trailhead Info: Drive north on Highway 36 out of town and turn right onto Longhorn Road. After one mile, the Boulder Valley Ranch trailhead will be on your right.
