We’ve camped at Tenkiller State Park once before and stayed in Shady Grove (rv area). This time we camped in Blue Jay on top of the hill. There was an issue with the power on the side of the loop we were on and we were not informed before we got there. They did offer to let us stay and refund our money which was nice. Thankfully, the weather cooled down at the time of our stay. The pool was not open when we went this time and it didn’t look like it would be opening any time soon. We stayed in site 131 ( water and electric only) and it was nice. We had tree line behind us and shade for some parts of the day. We don’t have a boat but we have kayaks and we went and put in on the north side of the lake and went out to goat island. The nature center and the gift shop are both small but nice. There is a walking path through the park and we hiked the overlook trail which is just outside the park. If you have small kids it might be more convenient to stay at one of the campgrounds closer to the pool and park.
