Brush Trail is a quick but bumpy way to access the water and camping at Rex Reservoir. The northern section is a scenic overlook ledge road, easily traveling into Fishlake National Forest. The road is primarily hard-packed dirt and wide enough for all full-size high-clearance vehicles. Camper trucks and trailers can safely travel the route, but attention must be paid when passing other vehicles. There is no camping to be found until the very end at Rex Reservoir. After rainstorms, the road surface can become extremely soft, creating deep ruts in the roadway.
