Facilities (camp store, restrooms, showers etc.) were clean and well-maintained. Great bike paths all over the state park to explore the army bunkers, Ft. Miles, and the beach. We rented stand-up paddleboards and explored the calmer waters in Delaware Bay (pro-tip, don't wear your wedding ring out there, or it may end up at the bottom of Delaware Bay…oops). We were out there in the afternoon, but the guy at Quest kayak rentals (right in the state park, at the fishing pier) if you go out in the morning, you can sometimes see dolphins!
This campground was pretty busy. You need reservations well in advance if you want to have a choice of sites in the summer. We got a site at the last minute, just for one night. It wasn't the best site and a little expensive for us (we tent camp and were in an RV site), but there was shade, free showers, and lots to see and do. We had a great time here!
We visited in early June. It's a large campground, with a mix of tent campers and rv's. When we arrived, we opted for the more secluded tent camping sites towards the back of the campground. While we were happy with our chosen site, what we should have done was snagged one of the spots on the western edge of the campground, which backs up against the AT and an incredible view of the sunset. Even if you don't opt for one of those sites, do yourself a favor and head over there in the evening to watch the sun go down.
We stayed in Longleaf campground at Congaree National Park for a stop-over on our way back north from a family trip in Florida. The campsites at Longleaf each had a fire ring and picnic table, and were pretty good sized. The key thing to know about Longleaf is that you need to be prepared in several ways:
We stayed in campsite 6 at Longleaf, which was great. Campsites 1-3 are closer to the lot, but also closer to the walk that everyone takes from their cars to their sites. For a little more space/privacy, opt for campsites 4 and above.
Although the campground is barebones, it had everything we needed and made for a great stop for us. Most of the park trails were underwater when we were there after a recent flood. It seemed like paddling would have been an optimal way to see the park and surrounding areas, but even so, we had a great time. There were lots of people out on the boardwalk trails, including lots of kids and dogs. Before you hit the trails, stop in the Visitor's Center and pick up the interpretive brochures on the types of trees/wildlife - they have kid versions and grown-up versions. Both were helpful in understanding the unique environment of the floodplain.
