I kayaked along the river and rested 1 night here. It is very hard to get from river level to camp site so be very careful especially if you are alone. The site is nice with maintained toilet, a fire ring, a table & nice comfy green grass. Too good for a free camping site. Surprisingly no bug/mosquito when I was here in mid Jul due to temperature dropped to 19 degree C.

Very nice camp site, plenty of wood if you are inclined to have a fire. Stayed at this site over night, was a decent place; however at the time of the stay the port-ta potty was infested with bee's. By this point in my ride of the C&O I had learned to have a good look around before going inside a port-ta potty.

Nice campground, but it cannot be accessed from River Road as directed by Google map. The nearest car access point is from Tayors Landing.

Plenty of flat area to put up your tent. Steep bank and/or staircase to get back on the trail. No cell service. One picnic table. Water was not muddy. Very picturesque site.

Great little campsite we arrived to it by river, it is difficult to access from the river little bit of a steep climb.. However there are three giant fish at least more than 18 inches lingering in the shadows wonderful spot for a fisherman. Has a porta potty and potable water. Will let you know tomorrow if it's frequented by an Axe Murderer.
