We rode from the top to bottom then back up to the top...kinda scary looking down the incline! We had a lot of fun...really beautiful views. Price isn't bad either....$10 parking when we were only there for about 30 minutes was a little annoying, but whatever.
Only reason I'm knocking off a star isn't even for the exact change policy...it's because there were no bathrooms! We had to go down the street to a fancy restaurant and ask to use their bathrooms.
I've always wanted to ride a funicular, and when I'm back in Pittsburgh I'll probably do it again :)
