Rockford © Alexbaumgarner
Illinois' second city, Rockford, set in rolling hills, is just northwest of Chicago. It is worth a visit for culture vultures and golfers in particular. The city is known for its 'cultural corridor' of which the highlight is the Rockford Art Museum's stunning permanent collection focusing on 19th and 20th century works. There is also a wealth of private galleries and historical museums in the city centre. Rockford is known for its antique shops and markets, and the many golf courses in the city and vicinity that have earned it the title of Illinois' 'holey' city.
