There are no Top 100 rides in the near vicinity and this is not a “destination climb”, but it is a unique ride that is worthwhile if you happen to be or live in the area.
Traffic and roadway: The roadway is very narrow, essentially a wide one laner the entire route. The roadway surface is in moderate to somewhat poor condition in spots. However, despite being fairly narrow, the road is safe as it has very little traffic. The descent is technical and caution is mandatory due to the incredibly steep grade and narrow width of the roadway. The road dead ends at a no trespass sign at the top, about 4.75 miles from the beginning of Mix Canyon Road.
