The facilities were great and the campsite was clean. The one reason that I will never camp there anymore is your camp host was mean. Very rude. Every time I had an interaction with her and accusing when I had questions. I wasn’t the only one that had this experience. Everyone that was in our camp party had the same exact experience with this woman. If camp host were changed, I would consider going back, but until that woman is removed I will not be going back to that campsite.

We had a great time. The campground Hostess was ever-present (which is a good thing) and the campground was clean and beautiful. We saw lots of wildlife and enjoyed the serene beauty of the area. Thank you!
