Go to the only stoplight in Divide on Highway 24. Turn north on County Road 51. Stay on County Road 51 for 11.0 miles as it becomes the Cedar Mountain Road. Turn right (north) onto FS 363 (also the Phantom Creek Road) (dirt) and drive for 0.6 mile until it hits FS 362 (also called Signal Butte Road). The Signal Butte Road is signed (as of Fall 2004). Follow FS 362 for 3.3 miles until you reach the trailhead for Signal Butte (marked). Park in the obvious parking area, and observe areas closed to vehicle traffic.
"The mountains have rules. they are harsh rules, but they are there, and if you keep to them you are safe. A mountain is not like men. A mountain is sincere. The weapons to conquer it exist inside you, inside your soul."
