I'm looking to car camp with my wife one of the coming weekends somewhere around Atlanta. We're both new to it and would really appreciate recommendations and general tips. Ideally, we'd love a place that is around 1.5-2hrs, has a water body or waterfall that we can swim in and not too crowded. We'll be camping from the back of our forester and wouldn't mind going a bit off the pavement to reach the place, if needed.

Our current setup is just an air mattress that fits in back, which along with some pillows and blankets should suffice for a night out in the current weather I feel. We don't plan on cooking or anything else at the campsite, just need it to be a night outdoors in peace.
