Rivers are the arteries of our landscape. But America's largest riparian systems once served as poster children for thoughtless industrial pollution. As these waterways, choked of oxygen and other nutrients slowly suffocated, so too did the downtowns that engulfed them. Once urban planners determined "we all live downstream," they set about transforming tidal cesspools into tree-lined aquatic oases, replete with cafés, terraces and verdant swatches for concerts and picnics. Late summer is the perfect time to discover and celebrate North America's river towns.

Charleston: A horse-drawn carriage along the palmetto-lined esplanade.
Charleston, S.C.
Charleston, S.C. is a city of islands perched between the Ashley and Copper rivers at their delta with the Atlantic Ocean. Once the shipping (and thus economic) capitol of the south, Charleston now offers Waterfront Park -- a half-mile stretch of riverfront that just 30 years ago was an industrial depository of pilings and parking lots. True to Charleston's 340-year old roots as exemplar of the Southern aesthetic, a palmetto-lined pedestrian esplanade provides almost a quarter mile of strolling not far from the restored wetlands that provide habitat for the aquatic residents of this historical city.
