Pine Creek Gorge, Wellsboro
It may be located in a very quiet and rural area but its breath taking to say the least... I've lived in the area for 34 years and I still love going up to the look outs and walking the trails. My kids love going and seeing the eagles fly around the gorge and the numerous animals and birds that are about the area.
Railroads seem to have went everywhere once-upon-a-time in Pennsylvania. The Jersey Shore, Pine Creek and Buffalo Railroad, created in 1883, used to haul timber, coal and passengers along the floor of the Gorge. The railroad was phased out in 1988 and the rail line has since been absorbed into the vast network of Pennsylvania's railtrails. Pine Creek Trail goes for 57 total miles allowing hiking, biking and cross-country skiing.
If you ever wondered why anyone would drive out to the Wellsboro/Tioga County region, here's a good reason. At about 800 feet deep, Pine Creek Gorge, dubbed "The Grand Canyon of Pennsylvania," is one of the more impressive gorges in the eastern United States. It is not a sublime sight, but is still very beautiful. The most scenic area, located west of Wellsboro on SR 660, are preserved in Colton Point and Leonard Harrison State Parks. Leonard Harrison is the more popular of the two. At the canyon, you can hike picnic, or just take in the view. The canyon was formed during the ice ages when glaciers dammed Pine Creek into a lake, eventually causing it to cut a canyon to the south.
SR 660 is a scenic road that connects the east rim of the Grand Canyon of Pennsylvania with Wellsboro. The road passes through farmland, forest, and "Animalland" which is one of those big-game wildlife parks (not something I'm interested in). It's a relatively beautiful road, and very worth driving.
