248 to Bowmans town exit.
Get off and head west over the Lehigh on 895.
Follow 895 till the first stop sign, an old gas station will be on your left.
Make a left (might be Mountain Road).
Follow that for a 1\2 a mile park is on your right.
FWIW, A few years ago I Camped and Hiked the Bake Oven section of the AT with my Family. We stayed at the Bake Oven Campground. Apparently they allow public fishing (to get the stocking truck to stop there). Anywhoooo, I caught two wild brook trout through that stretch after a campfire dinner on Saturday night. A nice surprise after litterally "Baking in an OVEN" during the day and night on that trip.
