“A Boulder mountain trail, more remote than the bustle of Chautauqua Trail or Sanitas Valley Trail.

The best way to reach Forsythe Canyon Trailhead from Boulder is up Magnolia Road, about a 45-minute drive. The run itself is relatively flat, and only has a few slightly technical areas of rocks. After following a shaded stream, you'll reach a very small waterfall, maybe 15 feet high. Follow the trail (uphill to the left) a little farther and you'll find Gross Reservoir.
Directions: Once you turn off of Magnolia and onto 68, drive for 2 miles then turn right into the parking lot just before FR359. Look for a gravel parking lot with a restroom and a wooden fence surrounding the perimeter.
