Not to hard to find. I parked at the small lot near Lock 38. Walked about 3 miles west and found the cave on the right hand side. There are a few much smaller caves before you get to this one, which are worth exploring. As for the campsite, when I walked through (late Feb) there was still a port-o-potty there and a seasonal water supply. Not an area I would set a larger tent.

Just camped there 4th of July 2020. The handle is taken off the water pump currently so no water is available near the site. There is a porta potty. The site is missing the picnic table. Good site to set up tents or hammocks. Right on the water with a beautiful view. Up river from the campsite about half a mile on the right you will see caves in the ledge. Fun to explore.

Not one of the best campsites on the C&O. Most of the ground is dirt which would turn to mud with a little rain. Most of the spots flat enough for a tent are on lower ground and probably prone to having water run thru them in a heavy or prolonged rain. There is one good spot on a berm right at the edge of the river bank. It has some grass on it, very soft dirt and slopes away on all sides which wi... Not one of the best campsites on the C&O.

There is one good spot on a berm right at the edge of the river bank. It has some grass on it, very soft dirt and slopes away on all sides which will drain runoff well, even in a heavy rain. The photo is my tarp tent pitched on this berm.

Nice spot to spend a night when it's not flooded. The cave just up the trail is fun to explore...

As the hiker-biker overnight campsites on the Towpath go, this one offer a bit more space and better views of the river. At the time of writing this, the privy is also in somewhat better shape than many sites on the Towpath, which is admittedly a pretty low bar. Likewise subject to change, the well doesn't have the overwhelming iodine flavor you get at some nearby sites.
