We stayed at Mcdowell Park Campground over a long weekend and really enjoyed it. The park is located southwest of Charlotte off of hwy 49 near Lake Wylie, SC. The hwy is busy and neighboring Lake Wylie is also busy. however, once you pull off the road and back into the nature preserve, all of the noise (except for airplanes) falls away.
Our camp spot was level and plenty big enough to accommodate our 12x17 tent. We had our own power and shared water with the next campers. We were close to the bathhouse which was really clean. We loved the laid back atmosphere. We even had a couple of families in a group camping next to us and across from us. And while their kids were "active" it didn't affect our easy weekend.
We were able to buy ice and firewood at the camp office. The staff were very nice and accommodating.
Others mention that there is not much to do. In the campground, there is a playground and not much more. However, the overall Mcdowell nature preserve has plenty to do with Lake Wylie, playgrounds, nature trails, fishing, and more. You can be as busy or as chill as you choose.
We are headed back in March 2020 to kick off our camping season.
