More than 600,000 people ride the M-Line Trolley along a trek through Dallas's Uptown, State Thomas, and Arts districts each year. The vintage trolley cars are a part of the city's transportation network, yet they're also a popular attraction for those visiting the city. You can ride for free, though "what you can pay" donations are appreciated. The areas along the trolley line are full of restaurants, must-see shops, and art museums.
