There are a large number of riding areas in the Region including Callahan State Forest and Mt Pisgah in the North, Douglas State Forest and Mendon Town Forest in the South, Hodges Village Dam in the West and the Vietnam Trail Network, West Hill Dam and Goat Hill in the East. It also includes a number of other riding areas in the towns of Millbury, Westborough, Grafton, Upton, Sutton, Northbridge, Holliston, Ashland and Hopkinton.
