1. Kanan Road
    Agoura -> Malibu. Nearly direct to Zuma, Free Zuma and Point Dume. Wide most of the way, easy drive, the tunnels are fun. Traffic from 3-5 PM in the summer, but it's not bad.
  2. Topanga Canyon
    Woodland Hills -> Santa Monica. Narrow, winding at parts. I've never been to any of the stores, but they look cool. Nice view of the Valley, Topanga Overlook is great at night.
  3. Las Virgenes Road/Malibu Canyon
    Calabasas -> Malibu. Fine, but Kanan is more direct to the popular beaches: Zuma, Point Dume, etc.
  4. Decker Canyon
    Westlake -> Ventura. Direct to Leo Carrillo, but narrow and steep, terrifying, horrible, nauseating. A great route to take if you want the adrenaline and catharsis of a near death experience without the actual physical danger of a near death experience.
