Get on at the top of the doubletrack or the Brook Trail
. Follow the singletrack along a little ridge and then you'll notice a number of rocks to navigate. The first few are at most 12 inches high and just exposed pieces of rock jutting up from the ground.
A few more turns and you get to a little rock chute. After that, enjoy some descending. At the fork, Knee Breaker
splits off to the right and Wild Side keeps to the left.
After that, the uphill slog begins. Two uphill rocky sections and some hairpin turns will get your heart going, but after that, it's smooth sailing until you hit the Red Blazes Trail.
