Located on two tracts owned by the Town of Marion and managed by The Trustees, these two and a half miles of forest trail traverse pine and oak uplands and unique wetland habitats.

An easement granted by the neighboring cranberry bog owner, whose active bogs are visible from the trail, connects the Town of Marion’s East Over Reservation to Hathaway Pond and the Town of Rochester, adding about a mile of walking trails to the existing system.

Take in a wealth of sights all around: a dramatic rock outcropping emerges from the forest floor, and an extensive elevated boardwalk gives up-close views of an ecologically sensitive area. On the northern trail loop, traipse across a stone slab bridge crossing over a small stream.
