Close to DC along the C&O Towpath Trail
If I lived in Washington DC, this is where I would ride my bike to every weekend. Bring the family, bring the fishing poles and forget that there is a hyper uptight city just a few miles away. This is one of the few hiker biker campgrounds with road access. And while this detracts from the privacy and "out there" vibe of so many of the other hiker/biker camps, the views of the river are truly stunning.
This was our final campsite along our 334.5 mile adventure from Pittsburgh to DC. In the morning we were awakened by the resident geese. We unzipped the tent to see a full moon setting, then later got up to watch the sun burn off the lazy fog on the river. Our neighbors were camping with 3 kiddos and 2 Great Pyrenees puppies, which made it all the more fun! And, the afternoon light was perfect for solar charging our power bank.
There are at least 6 separate campsites with their own picnic table and fire ring. Though with the increase in cars, comes a proportional increase in people and their trash. Pack it out people! There is city water access here which is not treated with iodine (like the NPS well pumps along the trail) so the taste is more palatable. The port-o-potties were clean enough.
The Great Falls of the Potomac area is less than 3 miles away on the trail and makes for an amazing day trip from the campground. There is also a rental Lock House across the trail which can be rented out and would make an easy getaway within 30 minutes if downtown.
