The Duquesne Incline is quintessential Pittsburgh. It's a fun little ride up and down the hill on the vintage cars, almost like an old roller coaster. Absolutely spectacular views of the city from the observation deck and the top. The station house has so much character, it's truly one of a kind. I really love that Pittsburgh is a modern city, but they keep the past well preserved. Bring your camera well, you will absolutely regret it if you don't.
