Good enough, conveniently located
Pretty standard campground—the perks are it’s location to nearby attractions and the river/creek. It depends on what you’re looking for—easy camping and proximity to Antietam and Harper’s? Golden. Especially if you want to camp but also do site seeing and/or paddling in the area.
Isolation and solitude, as well as good “car camping?” Not so much. The main problem here is that the campground itself is just one big field along the canal towpath, so you have no privacy from other campers. It’s also a weird setup with respect to parking—as you have to park on the opposite side of the canal and walk to your campsite. If you got one close to the bridge over the canal then you’re 100ft from the car, but if not then it could be a little bit of a walk. Not the end of the world, but it’s important to know what you’re getting into!
That said, enjoyed the experience here, but wouldn’t seek it out specifically unless looking for camping in this general area.
