I graduated from the University of Pittsburgh, and never took advantage of this lovely gem. We spent a weekend in Pittsburgh over the holidays and visited the Phipps Conservatory on New Years Day. It was beautifully decorated for the season! We walked through the entire place during daylight hours, went to eat, and came back to enjoy the lighted garden just after sunset. Spectacular!! It got busier as the evening progressed, but we were able to see everything before it got annoyingly busy (which was around 6 pm). The view of the Pitt campus was wonderful as well. I highly recommend a visit!
