If you're out and about in Chicago, chances are you'll catch a glimpse of them. No, not the famous skyscrapers or kayakers sifting for gold in the Chicago River, but rather the classic red and green trolleys and open-top buses of Chicago Trolley & Double Decker Co. As guides narrate cruises through the city's streets, passengers can see Navy Pier, Buckingham Fountain, and other iconic sights pass by outside.

Since its founding in 1994, Chicago Trolley & Double Decker Co. has helped millions of locals and visitors navigate the myriad landmarks, attractions, and hot spots that comprise the Windy City's 77 neighborhoods. The company's 75-vehicle fleet includes San Francisco–style trolleys and open-top double decker buses, both of which provide comfortable rides for sightseeing trips, hop-on–hop-off tours, and even private trolley rentals for transportation to special events such as weddings and parties.
