We spent a lovely weekend at Givhans State Park. It's definitely a small park, and its big draw is its location on the Edisto River, with lovely river-tubing to boot.
We stayed in the tent sites, which have water and electricity at each site. There is a central parking area, and then you must carry in your stuff to your site. Ours, T-28, was one of the first, and from the closest parking spot, it was 200 steps along flat ground (just to give you an idea).
The tent sites are right behind the only public restroom, which means that the restroom gets filthy after a day of the river-goers going in and out. There is only an outdoor shower. You can walk into the RV loop to get a larger, cleaner, and more private restroom with showers.
The only trash dump we could find (apart from the small cans in the restrooms) is located just off the entrance of the park. The park has a strong WiFi signal at the main house/office, but the rest of the park doesn't get WiFi and barely any cell service. The staff keeps the park clean and it's very pleasant, especially on weekdays! Don't forget the bug spray! And steer clear of the poison ivy, which is everywhere.
This is a great park. 30 foot trailer backed in no issues with plenty of room to pull truck in beside rig. They have some full hookup sites which is what I got. Most have water and electricity. They have RV and tent only camping. Lots of trees and shade. Would recommend going through the web site and making reservations. The only issue is no cell service at least for us and we use att and Google fi.
Small but nice park on the river
The park itself is nice, and the hike-in sites were private, which was nice. But they smelled strongly of urine, and were covered in poison ivy. We had children along for the eclipse, and it was nerve-wracking to worry constantly that they'd end up getting poison ivy.
