We really like that road that goes east from CA-33 thru Frazier Park too -- some truly magnificient stands of manzanita along there..

In that same area, the road thru Lake Hughes is pretty fun. Be sure and stop for a soda/brew at the rockhouse: http://www.roadtripamerica.com/eats/rockinn.htm

Another road this is fun is to follow 33 north and then turn west of CA-166 to Highway 101
