If you are in Western Pennsylvania and are a fan of Frank Lloyd Wright, you probably will visit Fallingwater. And, while it is spectacular, I think Polymath Park is the real hidden gem. Currently, it has two Frank Lloyd Wright Usonian homes and two built by his apprentice. Before you even visit the homes, the grounds of Polymath Park where the visitor center and the Treetops Restaurant is located are stunning and beautiful. Everyone who works there is exceptionally friendly too. A huge plus. You can eat at the Treetops Restaurant, literally, up in the tree tops. There is an also a bar, a pizza bar and more. There are several tour packages to choose from. I chose the two Frank Lloyd Wright homes. Relative to Fallingwater and Kentuck Knob, it was. bargain. And, what I really like about Polymath Park is that you can take photographs INSIDE the homes. At Fallingwater, they don't want you taking pictures inside. Also, on this tour you can walk into the bedrooms and other rooms. The guide takes you on a van from the visitor center to each home. And what I really like is this tour isn't crammed like it is at Fallingwater, meaning, you can get pictures without throngs of people and tour-after-tour in the way. You don't feel rushed at all on this tour. The super knowledgeable guide has all kinds of information and will answer any questions you have. It was really spectacular and I highly recommend visiting here. You won't be disappointed. read more
