We visited here on a Friday in early April. It was actively raining so we decided to not go on our planned hike. We did look at the couple exhibits inside the visitor center and looked at the store. The ranger and other lady at the kiosk were fun to talk to.
There is a video for the park they show in the theater on demand. It was a nice quick way to learn about the park even though we didn't get to hike and explore it much.
We also have been trying to collect all the VA State Park pins and unfortunately this park's pin is a bit underwhelming. It's a green shield with a buffalo and the park's name on it and it's very very small Almost the size of a button. We did end up picking up a couple of the cool looking stickers and a patch.
There are bathrooms and a water bottle filler inside the visitor center.
Definitely worth another visit to this park just to do a couple of the interesting looking trails. Martin's Station the historical living history area/fort was also closed on our visit. They are currently only open on the weekends.
