East Bay Bike Path, Rhode Island's oldest bicycle path, is also its most scenic. The 14.5-mile paved ribbon hugs the coast from Providence to Bristol, passing a wildlife refuge, salt- and freshwater marshes, an open panorama of Narragansett Bay — and at least five places where you can break for ice cream.
