Stayed one night on 8/9.
This is such a nice little spot right along the Potomac River. All sites are walk-in only, which means you park on the street, cross the bridge over the C&O and towpath, and then down a little hill to your site. When my dog and I arrived, someone was still there, but after letting them know I had this spot reserved, they promptly packed out. There were no camp hosts on-site and nowhere to check in.
There isn't much privacy between you and your neighbors (or the C&O towpath so be prepared to see bikers, walkers, and runners). Each site has a grill, fire pit, and picnic table. I stayed at Site 11 which had its own path down to the Potomac River. It was quite steep for my bum knees and ankles, but I saw kids easily run up and down it. The Potomac is mostly flat with some "swirlies" for experienced paddlers. I also saw some people tubing.
There's one bathroom area- 2 pit toilets and 2 portapotties. There is nowhere to leave trash, so be sure to follow Leave No Trace principles and pack everything out with you. The sites are fully or mostly shaded. Be prepared to make friends with bugs, but they shouldn't bother you. Also great news- no mosquitoes!
I have Verizon and had better service by my car on the road than at the actual campsite. At the site I could make calls but couldn't check the internet. Other than a few check-in calls to family, I was looking to unplug for the night.
I ended up not sleeping overnight due to a personal health issue, but I am looking forward to coming back when it's a little cooler.
