Oldenburg Point Viewing Deck

From a parking lot which is part of Jay Cooke State Park, an easy trail leads (maybe 250 yards) to a viewing area high over the river. From here you can see upstream all the way to Fin Falls (in the distance).

Boaters who have run this lower part of the river (who did not get out at Swinging Bridge/Fin Falls) have a long, steep, grueling climb up a rugged (unofficial) trail up a gully to make their way up to this viewing area and back to their shuttle vehicles.

Topo maps list the summit height near the parking area as 973', whereas your river-take-out is something near 710', so you are making about a 260' climb in  about a quarter-mile!
