The Upper Charles Trail (UCT) is a 26-mile multi-use trail system under development, linking the towns of Sherborn, Holliston, Milford, Hopkinton, Framingham, and Ashland. Currently, 13.7 miles are completed, including prominent sections like the Milford and Holliston trails. Once finished, the UCT could connect to the Bruce Freeman Rail Trail, the Mass Central Rail Trail, and larger networks like the New England Greenway and East Coast Greenway.
