It's great to have a campground this close to D.C. so you can do day trips to all the sights around. Visited the Wharf area in Baltimore while camping here. The code system and entrance gates are a little tricky, but are needed for safety in the middle of this metropolitan area. The showers could be cleaned more frequently but the water was good and hot. The hosts seem diligent and available. Fi... It's great to have a campground this close to D.C. so you can do day trips to all the sights around.

We had to use levelers for our site at 418. Great for families.

Great staff, very friendly. Nice wooded area. I did find the sites to close to each other. Great if you like to make friends, but not so good if you enjoy keeping to yourself. Overall it was very quiet and well kept. Bathrooms do need help. There was a sign on the door that renovations are coming. Some sites have electrical hookup, but no water.

I love this little gem near Baltimore. Dog and family friendly. Electric sites and primitive sites. Ice on site and firewood on site 24 hrs on the paybox honor system. Dated but clean restrooms and plenty of trails for hiking and biking. River for fishing. And quiet and dark at night. Park staff are awesome.

The staff was great but the website is super misleading. All the pictures are not of the actual campsites. So I thought i was renting this nice looking wooded area. What i got was this spot that literally has the driveway of another spot backed right against it. Thankfully they had 4 other posts available and they let me look at them all and transfer to the one i liked the best. The staff was supe... The staff was great but the website is super misleading.
