J. Harry Rich State Forest is a state-owned tree farm that covers 507 acres of land in the Town of Groton and borders the Town of Pepperell. The forest is named after John Harry Rich, a former State Forester who was instrumental in acquiring land for the Quabbin Reservoir, one of the largest public works projects in the early 20th century. The forest offers visitors a chance to enjoy hiking, biking, fishing, and wildlife viewing. The forest has a network of trails that pass through diverse habitats, including wetlands, woodlands, and fields. The forest also protects the watershed of the Nashua River and Cold Spring Pond.

The AllTrails website has a description and map of a hike using the John Tinker Trail.
