About Chicago
Chicago is America's most underrated big city — a walkable lakefront, an extraordinary skyline, some of the world's best food, and a cultural scene that punches far above its size. The free Chicago Riverwalk and miles of lakefront trail make it surprisingly easy to have an excellent time here without spending much at all.
Visa: Domestic — no travel documents required.
