Swamp Walk

I just discovered this place a few days ago, and it has become my new favorite place to run. This path is the remains of abandoned train tracks construction ending in 1981- thus, given the name "Rail Trail". It passes through Topsfield, Wenham, Danvers and more. Less than a quarter of a mile from the Topsfield  trail head is a sign for the "Swamp Walk". An elevated bridge passes through the swamp for less than half a mile. It is one of the coolest places I've been. Check it out.
