The Holliston Rail Trail runs across Holliston from the Sherborn to Milford town lines. The Milford Trail is paved and connects seamlessly from the Holliston Rail Trail at the town line then runs to the Hopkinton town line.

The Holliston Rail Trail accommodates a variety of non-motorized uses such as bicycling, walking, jogging, wheelchairs, and cross-country skiing. The use of motorized vehicles on the Trail is prohibited but Ebikes are permitted (Class 2 and below) and speeds must be kept low, below 20 mph.

The total UCT trail system length depends on the final route of the trail and what towns join in. If Framingham joins in there is the potential to connect the UCT to the Bruce Freeman Rail Trail which can then connect with the Mass Central Rail Trail. Parts of these trails would then become sections of the larger New England Greenway and the East Coast Greenway running from Florida to Maine and beyond!
