A fun little section of trail that's over all too quickly. Starts with a semi-steep series of switchbacks, before opening it up a bit onto some longer straighter sections. Ends by riding uphill past the dam, and down the road.

The trail seems to be mostly used by bikers and horses, and is reasonably wide + smooth. Its fast and has good gradient, but not so steep as to be punishing. With a little trail work to make better berms/angles on the switchbacks, and to buff out a couple of the fun water bar jumps, this could be one of the best trails around.
