Campground has a great layout and atmosphere for the last few years that I've been here. There are different groups of people that always seem to be friendly. There are different sections of camping spots, some with access to the river down the backside of the campsite and others across the lawn in a more quiet area, as well as the wooded section which itself does appear to be more quiet and dark towards the night hours.
I will highly suggest if you visit during/around the weekends of the 4th of July that you bring ear plugs and/or don't expect to sleep without issue. This past year we had fireworks going off into the early hours of the morning and I believe they were eventually told to leave the campground. I would have liked to see a lot more push from the management as these were two groups shooting off fireworks well past midnight and dangerously close to the ground as well as over the water while people were floating by.
Strongly advise visiting outside of the 4th of July window for best experience. The rafting trip is great as well, floating down the river for 3-4 hours is a nice way to spend a day and relax with slow moving current that is safe.
