🏆 Urban River Revival — 3.5-mile trail along the revitalized Neponset River — from industrial wasteland to urban greenway
Lower Neponset River Trail follows 3.5 miles of the Neponset River through Dorchester and Milton — transforming a former industrial corridor into one of Boston’s finest urban greenways. The paved trail passes historic mill sites, salt marshes, and the Baker Chocolate Factory — where America’s first chocolate company operated from 1765 to 1965 (200 years!). The Neponset River estuary supports great blue herons and snowy egrets within sight of downtown Boston.
