South Sourdough trail is near the the town of Nederland and is a more lightly traveled area than others. You'll start this ride at the trailhead a mile up County Road 116 off of the Peak or Peak highway.

BMA rates this ride as a intermediate-advanced. There's decent elevation gain and tons of rocks and roots. In the winter, this is a good fatbike ride, though about 3 miles in it's often unpacked and hard going. Then the closer you get to Brainard, the more travel and packed it becomes again.

This ride takes you 6 miles to the Brainard Lake area, then flip your bike around and pedal back to where you started. If you need more miles, there are lots of trails starting at Brainard, including the rest of Sourdough that runs all the way to Camp Dick.
