I've never ridden the whole trail, but I've ridden in that area, and it's really nice. Highly worth further investigating. And it's not far from here.
The Oil Creek and Titusville railroad north of here does the same thing.
Caution, there's some pretty bad audio;
I've always wanted to park a bike at the south end of Oil Creek, kayak down from the north, bike back, and then I guess just take the train ride for the helluvit. Sort of a steam triathlon.
