Trail Overview

The West Silica Hill Road SFR 645 is a 1.3-mile-long forestry road through Shawnee National Forest. As you travel the road, grades come in waves from gradual incline to steep grades. These steep grades include tight turns, medium-sized ruts, bare dirt sections, and some mild water collection spots. In a few areas, the gravel becomes thin and the dirt takes over, creating soft spots in the road. The drive to the top leads straight into the middle of the Rock Top SFR 233, which has some of the best views of the area. With rain and wet conditions, the difficulty of this trail only increases.


The main difficulty is crossing ruts while climbing the steep grades, just have to be mindful of keeping momentum but not pushing too hard straight into a rut.
