Mulholland is nice, but way too crowded.

I like Glendora Mountain Roads since it has three sides with one side not being too populated.

 

That is just possibly the worst road in southern California as well as Angels crest road, and my reasoning for saying that is due

*inexperience drivers
*narrow
*lots of cops
*lots of fatality on that section


dont get me wrong its a nice driver road but never will drive it again.

 

I agree. I took my bike there. It is ok for a bike because it is small but only one road, i'm not sure which way but one doesn't even have a lane, its just one road from Glendora to Montclair. The road we took on super car Sunday, the Malibu canyon run road was great. Lots of twists up hill and downhill and puts you right at the beach.
