  • This campground was so great! The employees were so helpful and the visitors center was small but still really cool and informative to walk through. It tells you history about the area. The campgrounds themselves have enough room for a car/camper/trailer and have water and fire pits and a picnic bench. When I went, I just had a car and a tent and it was plenty of room. There are bathrooms located in the center of the campground along with showers. The bathrooms were extremely clean, by far way cleaner than any campground bathroom I’ve been in. My boyfriend and I were both very impressed by the cleanliness of them. Best of all, there are areas with signs telling additional history about the area if you know where to look (or happen upon it like I did). Definitely would love to visit here again!
  • Great for RVs, but camp sites are literally on top of each other. I've never seen a campground so cramped. We even had to share our fire area with our neighbor. River access is great for boats and fishing, but no real access for swimming.
