Re: Central Pa Hiking Trails
You can call the DCNR and get state forest maps (some SF have hiking trail maps too) and they are free. They will show you trails and trail heads.
There are also books for sale on hiking trails in PA, some for different regions of the state. They are nice because most give trail descriptions/ratings, directions and/or GPS coordinates, info such as waterfalls, vistas, etc.
