The gateway to the newly revitalized waterfront is the Rose Kennedy Greenway. Where once was a hulking overhead highway, now winds a 27-acre strip of landscaped gardens and fountain-lined greens, with an artist market for Saturday shoppers, and food trucks for weekday lunchers. Cool off in the whimsical Rings Fountain, walk the calming labyrinth, or take a ride on the custom-designed Greenway carousel.
