Bayshore Boulevard Trail. Considered the world's longest continuous sidewalk, this 4½-mile trail is a good spot for just standing still and taking it all in, with its spectacular views of downtown Tampa and the Hillsborough Bay area. Of course, you can also walk, talk, jog, bike, and in-line skate with locals. The trail is open from dawn to dusk daily. Bayshore Blvd., Tampa, Florida, 33629. 813/274–8615.
