Knoebel's is far from any large cities, down on the edge the Pennsylvania "coal country" (as my friend from Beaver Springs used to describe the area).
Closest city of any size is Bloomsburg, and even that's not too big. Actually a very nice town.
No interstates go there, or anywhere near. Just winding two-lane roads.
Probably not much in the way of "public transportation", either. If any at all.
THAT'S why it remains a nice place to visit...
