Cheap and very beautiful in the 🌅 but a bit noisy at night with geese, airplanes, helicopters, car traffic, and owls.

Several Big Sites! Plenty of room for anyone hiking or biking the C & O. Closest campsites to DC less than 10 miles out of town. Note: There is airplane noise throughout the night and it is a bit inland from the rivers edge

Campsite 1, 2 and 3 are left off of the foot bridge. 4, 5 & 6 are to the right and are closer to the bridge. All camp site areas are big and have a bike rack. Water is just over the foot bridge. We use a fold up wagon to make life easier. Parking was not a big issue, we hade two vans, a pick up nd trailer and a mini van and a Jeep. We also had 3 camp sites book, so not a lot of competition.... Campsite 1, 2 and 3 are left off of the foot bridge. 4, 5 & 6 are to the right and are closer to the bridge.

The walk from parking the campsite was more of a hill and longer than I expected. Lots of steps as well, but doable. Lot so traffic on the tow path, but nothing major. Other than the being in the flight path of the airport, and of course the bull frogs, not a lot of noise. I would Suggest for the the price, if you are a scout troop, renting 1, 2 & 3 OR 4, 5, and 6 so you have the whole are to yourself.

Convenient camping spot for youth groups. You have to pack in all your gear but it's a short hike. Great area for firemaking and lots of firewood from fallen trees. Then you're right on Billy Goat B trail for some good hiking.

A great little campsite that is about 3/4 of a mile walk from the Carderock Parking area. Take the Billy Goat C trail from the parking lot to the C&O towpath. Then take the towpath until you see the sign on the left for the campsites. This is about 100 feet past the Billy Goat B trail sign. Potable water is up the towpath in the opposite direction of the parking lot across a foot bridge. Great loc...

Saw a bunch of blue herons while I was there.
