Hey – there are a number…
– Allegheny Front Trail – 27 mile loop near State College
– Old Logger's Path – 27 mile loop 30 minutes north of Williamsport
– West Rim Trail – 30 mile point-to-point outside Wellsboro (there's a shuttle service to move your car so it can seem like a loop)
– Black Forest Trail – 42 mile loop south of Wellsboro
There are a number of others that would require a car shuttle.
Please feel free to PM me if you have questions about the trails or would like to see photos.
