This 1-mile out-and-back shoreline trail in South Acton offers excellent fishing access with numerous good fishing spots (valid Massachusetts Fishing License required) and features a 180-foot boardwalk with an observation platform and bench about 130 feet from the small gravel parking lot.

The mostly level trail follows the Assabet River just upstream of historic Powdermill Dam and continues across the town line into Maynard, with abundant wildlife viewing opportunities including bald eagles, herons, and river otters.
