The Sly Park loop is a beautiful ride around Sly Park reservoir. The ride starts with a fire road climb, followed by a very fast and fun descent, again on a fire road. The fire road is littered with water bars that make for exciting jumps - just watch out for small tree branches hanging where your head will likely pass when you're airborne. This descent ends with some tight, loose single track switch backs. At this point, you've reached the lake, and the trail stays along the shores of the lake for the rest of the loop.
