DCR's Charles River Reservation is a linear park stretching from Boston Harbor up the river for 20 miles. The lower half of the reservation, from downtown Boston to the Watertown Dam, is the Charles River Basin , which includes the Esplanade on the Boston side. The basin abuts the campuses of MIT, Boston University and Harvard. The Upper Charles Riversection of the Reservation begins at Watertown Square and meanders to Riverdale Park in West Roxbury.
The Reservation has many recreational opportunities for urban dwellers. Whether your interest is walking or birdwatching, canoeing or in-line skating, the Charles River is a wonderful resource.
