Is it paved in the lower section?
I don't think I have traveled on that one. Is it paved all the way down the slope?
You have to drive the Ridge Route. It is a classic.
Harrison Scott -- Ridge Route Historian
Harrison Scott is credited with almost single-handily "saving" the Ridge Route from total deterioration. The most scenic section of the route starts near Castaic. Going northbound, exit I-5 at Parker Road and turn right. This is the start of the Ridge Route. The road winds thru the mountains and eventually reaches CA-138 where you can turn west to return to I-5 at Gorman. A great web site has maps and photos at http://www.ridgeroute.com/
Enjoy!
