Even if you're in fighting shape, climbing up steep slopes is tough work. Ride Corcovado Train and get up the mountain quickly and comfortably. The views are nicer too!
Situated in Cosme Velho, this incline railway is worth including in your schedule. But you'll find lots more to see and do in the area. Christ the Redeemer, Sugar Loaf Mountain, and Maracanã Stadium are within close reach of Corcovado Train.
