An absolute must stop when visiting the wonderful city of Pittsburgh. You know when your friends say "you must stop here when you visit - insert city here." Well, The Duquesne Incline when visiting Pittsburgh is one of these stops.
Inexpensive (bring cash like previous Yelpers have mentioned) and not a huge time commitment. The views of the city are absolutely spectacular and well worth the time investment. There are also a few restaurants close by if you want to grab a bite or drink and continue to take in the view.
A great spot to to take in the gorgeous views of this very underrated city. Enjoy...
