Overall, the Antietam Creek Campground was nice and well-maintained. Spent two nights there with my scout troop. The facilities are on par with other campgrounds, but getting water was a haul because we were at the far end from the pump. Fortunately, we had plenty of able-bodied scouts with us to fetch water 😂. The major downside were the nut trees: black walnut and another I couldn't identify.... Overall, the Antietam Creek Campground was nice and well-maintained.

Fortunately, we had plenty of able-bodied scouts with us to fetch water 😂. The major downside were the nut trees: black walnut and another I couldn't identify. The ground was littered with nuts, and they dropped randomly the entire time we were there. Another adult with our troop took a small one to the head, but he was ok. I don't think much can could be done about it, though; I'd hate to see perfectly good trees cut down over that. O

Great for primitive camping near Harpers Ferry. Some campsites have access to the river. We had site 4 which had a nice spot for a hammock along the River. I hear sites 18 & 19 also have decent access. Plenty of shade in the spacious sites. Note that there are no showers. The biggest drawback for this campground is the most direct access to many of the sites from street parking is through a steep... Great for primitive camping near Harpers Ferry.

Note that there are no showers. The biggest drawback for this campground is the most direct access to many of the sites from street parking is through a steep ditch with no stairs. You can go around on the bike path, but it could add some distance to your trek with all your gear.

I stayed at camp 7 and it was comfy, near the latrines and on the Potomac river. Gnats were horrific this time of year, I'd recommend some bug repellent for the day time, night was pleasant and quiet overall. They had a BBQ station, picnic table in good shape, and a small and large fire pit in this one. Perfect for a group to gather at. These are walk-ins but for this Adv rider it wasn't difficult...

Grassy area for pitching tents. Picnic table and fire ring. The water well and pump are at the north end of the campground. Bathrooms in the middle. Some access to the river.

Lovely campground right on the banks of the Potomac. Definitely off the beaten path, but well maintained. Access can be a pain with the Canal between the road parking and the sites, so bring a cart or wheelbarrow.
