Charles River Reservation
“The Upper Charles River Reservation extends from the Watertown Dam to Riverdale Park in West Roxbury, MA. Now that native plants have been restored to the riverbanks, birds and wildlife have returned. You can follow paths that wind along the Charles River, through the towns of Watertown, Waltham, Newton and Weston.”
