This is a wonderful bicycle path. First, you must ride prepared with water and be prepared for climate change. It can get several degrees warmer and you can get wind at the lower end.
You can do the entire path or go you to a point and turn around. I like to start in downtown Ventura and end in the arcade in Ojai. Once at the arcade you can treat yourself to breakfast, ice cream or even a glass of wine.
The path is pretty shaded but it does have a few occasional rough spots or debris, so watch the path, but it is way better than cars.
