This place looked promising at first. I arrived on a Friday night and there were multiple tent sites available. Very pricey, but Charleston accomodations are like that, and the park looked pleasant and well developed. I set up my tent and was happy... at first.
Right after I went to bed, a major thunderstorm rolled in. I'd weathered such storms before, and my tent usually performs well. My campsite had a raised tent platform filled with sand, which I assumed would drain well. It did not. The tent was "floating" for a while. Standing water under the floor. Only a little water leaked in, luckily.
When I got up in the morning, the tent pad had mostly drained, but the rest of my campsite had turned into a swimming pool. I walked around the campground and it looked like my site was the only one that had flooded like this. "No problem," I thought, "I'll just book a second night in one of the other campsites." Nope. They were booked solid. Had to pack up my wet equipment and never really got to enjoy the park.
I imagine this could be a very nice place to camp under better conditions, but I did not have a good time.
Side note, there was a chorus of extremely loud frogs here that kept me awake at night. Cute but annoying.
