Went here at the end of May and during a non-holiday weekend hoping to beat the heat and the crowds. We had good weather though it was a bit hot during the day and no wind. Duke's was a nice campground. It didn't have as many people as the other campgrounds around Lake Murray had, but it wasn't really close to the water. We tent camp but spent our stay at an RV spot. Having electricity and water nearby was nice. Tent camping sites were about 100yrds from bathrooms. Our site was a bit closer but not too close. Tent sites are first come first serve. RV spots as well but you can reserve them. Sites were fairly clean. Picnic tables are cement and pretty uncomfortable. Some RV sites were challenging to find places for a tent. If you like being away from people, with some slight separation from others, this was nice. The people managing the location were nice. Bathrooms were pretty good though it would have been nice if they would use a broom once in a while to clear out the spiders and other insects. Lake Murray is a nice place to visit. Hoping to return again!
