More ways to explore the area's outdoor wonders
You step off the bright Chicago sidewalk and into cool concrete shade—the Pedway’s tunnels, stairwells and glass lobbies immediately change the city’s tempo. For two hours you move beneath street level through a hidden circulatory system that threads forty downtown blocks, surfacing into unexpected interiors: the carved stone of City Hall, the vaulted retail spaces beneath the old Marshall Field's, and quick glances at public art like Picasso’s monumental sculpture before slipping back underground.
