A city tour by helicopter is a really unique option offered in most larger cities. These tours provide a unique perspective of the city but, of course, don't give you a chance for a really close up view.
Trolley and train tours of the city are available in some areas and cities, depending on the size and features of the city. These tours usually provide meals and refreshments and some may even offer stops at famous restaurants and food areas.
Believe it or not, you can book your own city tour and guide yourself through it. Many locations offer city tours that are simply rented equipment that will take you around the town and tell you great bits of information that you need and want to learn.
