We enjoyed the round barn however it was extremely hot and there was no air conditioning. There was no fee however you could donate if you chose to. The staff was very nice and I enjoyed all the artifacts and museum items they had on display. We didn't stay long because of the heat but I'm glad we went!

The Arcadia Round Barn is directly on 66 and has plenty of free parking to make an easy stop at. The Round Barn is a really cool structure that has a bottom floor, top floor, and exterior public restroom. It is free to enter and they accept donations. The bottom floor is mostly filled with a gift shop. The gift shop is kind of a hodgepodge of things from thrift clothing to 66 merch. The second floor is what most visitors will want to see. Not much up there, but it does allow you to see the neat circular structure of the barn. According to a sign, they occasionally do music up there if you're lucky. I wouldn't classify this as a must do, but it still should be high on any 66 to do list since it will only take you 30 minutes or less to see and is a one of a kind sight. For non-66 travelers, this is only worth a short detour to see, but is still better than most anything you'll see in OKC.

The Round Barn was one of my favorite stops while traveling Route 66 through Arcadia, Oklahoma. The historic red exterior makes it an iconic roadside photo stop, but definitely don’t leave without exploring inside.The lower level has a wonderfully rural, museum-like atmosphere, with displays and memorabilia that help tell the story of the barn and its place in local history. It feels authentic and perfectly suited to a historic Route 66 attraction.Upstairs was the highlight for me. The entire upper level opens into a large entertainment space beneath an absolutely stunning wooden dome. The intricate construction of the roof, with its beams radiating overhead, is remarkable. Be sure to look up and take some time to appreciate the craftsmanship—it’s also fantastic to photograph!The combination of history, architecture, and classic roadside-Americana character makes The Round Barn much more than a quick photo opportunity.If you’re traveling Route 66 through Oklahoma, this is a stop I would absolutely recommend.

The upstairs is absolutely breathtaking. The bottom is a gift shop with some history to go along with it. It is run on donations, so please leave a little. The parking lot is a little hard to wind around to. This is a must on Route 66.

A must stop on Route 66. It is really neat inside and the staff was super nice.
