For more than 50 years, CAF has been celebrating Chicago’s magnificent architecture. The foundation offers 85+ docent-led tours, including Chicago’s most popular river cruise and many downtown walking tours that depart from its current location at 111 E. Wacker Dr., above the CAF River Cruise dock. Opened this summer, this space has become the Chicago Architecture Center inside a historic Mies Van Der Rohe building. The center is an exciting destination for visitors and Chicagoans alike, with new exhibits, a lecture hall, a design studio and a gift shop. Open daily, 9am-9pm. Tour prices vary.
