Ferdβs Bog is a 1/3 mile nature trail, access from Browns Tract - Uncas Rd outside of Eagle Bay. There is a scenic view of the Eagle Creek from the end of boardwalk.
A lot of the trail, especially through the notch south of Grand Gorge reminds me of the Old Erie Canal, although it never was a canal -- it's just the East Branch Delaware River is channeled between the old rail grade and state highway.
