Assabet River Rail Trail

The Assabet River Rail Trail is a paved path on an old railroad line in two open parts: about 5 miles from Marlborough to Hudson, and about 3.4 miles from South Acton through Maynard to the Stow line. The two parts do not connect yet. People use it for easy rides and walks between town centers, ponds and the Assabet River.
