Came on a lovely spring April day and wish we had more time!
We spent about 2 hours briskly walking through the grounds (we were on a time crunch). Please allot more time to read every little sign, and take in the great care of this place! However, if you're short on time, there is a nice little garden to stroll around (for free).
A lot of stations for kids (arts and crafts) were open on the weekend and activities seemed to encourage little minds to learn and explore YET had a little something for all ages. Lots of chihuly glass which was neat too.
Tip: if you visit often or live in Pittsburgh, get the membership! You can use what you paid and take your receipt within 7 days to use towards your annual membership fee.
