Depends on What You Are Looking For
This is a fairly nice, bare bones NPS campground. If you are really looking for somewhere to feel far away from civilization and see some beautiful scenery, this probably isn't it. Helicopters and planes fly over regularly, and you can hear sirens from neighboring college park. The campsites are pretty close together, we could see probably about 10 or so other campsites from our campsite. And there is not a ton to do within the park itself -- there are a few picnic areas, a pretty unimpressive small playground, some nature/walking trails, and that's about it.
But it is a pretty nice campground -- campsites and showers seem clean and well maintained, bathrooms are fine and you're never far away from one. Rangers come around regularly to check on things and every one we interacted with was extremely friendly. I don't think there's anything comparable so close to DC, so if you're in the DC area and just want someplace close by for a short camping trip, or are looking for an affordable outdoors-y option to stay while you're visiting DC from out of town, this probably fits the bill. As soon as you leave the park you are in College Park with Metro access close by, and very close to the Baltimore-Washington Parkway.
