If you want to mountain bike in Ventura County, then Newbury Park is the best place to start. The area is littered with trail of all sorts, you can literally ride out your back door and catch a trail only a few minutes away. And mountainous trails, not just hills. When I was there the trails were wet from massive storms so I was limited in the places that we could ride, but still had a great time. I will definitely be coming back again.
