the areas that I am talking about are located in the eastern areas of O.C. You can take Chapman Ave. east and go out towards Irvine lake area. Chapman Ave. turns into Santiago Canyon Road. Take that pass Irvine Lake and look for the signs for Modjeska Canyon or go to Santiago Peak area. If you are new to this, take another vehicle along.
If you have a Thomas Guide for O.C. you can look it up on their. I live in the city of Orange, right in the heart of O.C.
