Charles River Reservation is a park extending from Boston Harbor up Charles River for 20 miles. It touches recreational properties and parks in Boston, Cambridge, Watertown, Waltham, Newton, Weston, Needham, Wellesley, and Dover. Recreation in the reservation includes walking, bicycling, bird watching and water sports like rowing and paddling.
The part of the reservation from downtown Boston is the Charles River Basin, which includes the Esplanade on the Boston side. The esplanade is the location of the July Fourth concert. The Upper Charles River section begins at Watertown Square and extends to Riverdale Park in West Roxbury.
