Philadelphia's headline sights cluster in a walkable few blocks around Independence National Historical Park — Independence Hall, the Liberty Bell, Constitution Center. Beyond the history, the city rewards walkers: run up the steps of the Museum of Art like Rocky, wander the aisles of Reading Terminal Market, or tour the ruined cellblocks of Eastern State Penitentiary. Fairmount Park — one of the largest urban parks in the country — stretches along the Schuylkill, big enough for a full day with a bicycle.
