My second time coming here, was just like the first one, very good. Scenic view, nice slow trolley going up and not so much wait, makes it perfect.
Breathtaking view of Pittsburgh from the top here, have attached some pictures. A must see and do to experience when in pittsburgh. Tried to look for Pittsburgh Steelers stadium from up there, but probably didn't recognize it. The trolley service is good and prompt. It runs till 12:30 am so you are never too late to be here. $2 something for adult so not a bad option with price as well.
View is just too good to resist. You can take a look at the history by going through the museum they have up on the mountain when you leave the trolley.
Go for this guys, the downtown is really cool and vibrant. Photographers paradise.
