Cross over the bridge and carefully cross to the north side of Foresthill Road. About 1/2 mile from the bridge there is a small trailhead. Go under the bar and take this trail (Fuelbreak trail). Fuelbreak takes you to what I believe is the highest elevation of the ride. There are some decent views up here but what this section of trail is really about is suffering.
