South St. Vrain Trail (West)

Trail Meter: 

If you're in the mood for a technical feast, then this is the place to be. Although the trail is not steep overall, it is best ridden downhill, meaning west to east. Embedded rocks sized from grapefruits to washing machines abound. The rocks, water bars, and occasional steep section will command your attention the entire time.

Views are scarce as the trail wanders along a forested, low contour on the South Saint Vrain drainage. You may see an occasional moose, Tufted Squirrel, or Gray Jay.

The very beginning of this trail used to be in wilderness area, meaning it was a no-no for mountain bikes.  Luckily, your friends at the Boulder Mountainbike Alliance fixed that a few years ago; BMA worked with the USFS to reroute the trail out of wilderness (and into a much better, sustainable location) so that mountain bikes could join the fun legally.
