One of the first stops you may get to is an outlet mall. Here are the directions from their website;
Camarillo Premium Outlets is located just 45 minutes north of Los Angeles and 40 minutes south of Santa Barbara.
Take Highway 101 to Camarillo, exit Las Posas Road. http://www.premiumoutlets.com/outlets/directions.asp?id=20
If you don't live near a big outlet mall, this is one of the better ones. But be ready to spend at least half a day, unless you are really fast shopper. We found parking to be more difficult than necessary, mainly due to the sheer number of people. As much as we love shopping, we decided to focus on the drive on this trip. We did get a great burger at In-N-Out Burger near the outlet mall. As we live on the East Coast. It is a treat when we can get animal style at In-N-Out Burger. I have to say that I still think the In-N-Out Burger on Sunset is the best one.
