After the turn you will follow the trail towards the trail head parking lot located near the Cool fire station. Along the way you will have three creek crossings.

After leaving the aid station you will continue to cross open meadows with oak tree groves all around. At mile 3.7 you will come into a large meadow. The trail will climb for a short distance at this point. The climb finishes inside a large oak tree grove.
As you come out of the trees the trail will roll a little as you approach a right turn. As you make the turn you will start a rolling half mile downhill.
Soon after the down hill you will turn left and head towards Knickerbocker Lake. You will follow along Knickerbocker Lake a short distance before leaving it behind.
