The Appalachian Trail covers 230 miles of the southern most mountain in Appalachian mountain chain in PA. In the Lehigh Valley area the Mountain is referred to as the Blue Mountain. Here are some shots I’ve taken along the trail in PA.
Bear Rocks is west of Bake Oven Knob about 2 miles which is 8 miles west of Lehigh Gap.
Lehigh Gap is where the Lehigh River Cuts through the Blue Mt. PA State Route 248 also goes through here.
Hickory Run State Park is also photographed here with the Boulder Field shots, but I have waterfall photos from the park in their Own Gallery. Hawk Mt. Sanctuary has some beautiful lookouts and challenging hikes.
