F. Gilbert Hills State Forest is adjacent to the Harold B. Clark Town Forest to its north, and is connected to Wrentham State Forest to its west. The "minimally developed" Franklin and Wrentham state forests are managed in conjunction with the Gilbert Hills property.
Contained on state forest land are some unique stone structures that some believe were made and used by the native Algonquin tribes prior to the town's founding.
