Beautiful campground, fairly large with 4 separate loops. Loop A is for organized groups/youth/scouts, Loop B is for tents and RVs under 30 ft, Loop C is for tents, and Loop D is for tents and RVs under 35 ft. No hookups at any of the sites.
There’s a dump station and drinking water fill in loop C (sorry tenters who wanted to avoid RVs). The water fill was a little annoying in that there’s a handle you have to hold down the whole time, but we used a rock to prop the handle down.
The bathhouses are ok, happy to have free showers with hot running water. Faucets allow you to control the temperature and there’s continuous running water (no button to push). There’s only one large shower per bath house, and you only have a curtain (no door and no lock). Sites vary in levelness, some are fairly level and some are on a mini hill. Driveways are all very narrow. Most have too much tree cover for solar or starlink, but some sites are more open and you might be able to make it work. Each site has a picnic table and fire ring. Cost is $20/night, must reserve on recreation.gov, and you can do that when you arrive and pick a site (no service fee for this site)
Cell service is pretty good for Verizon and ATT.
No alcohol allowed in the park.
GETTING TO DC: There’s normally a walking path from the campground to the metro station that takes you into DC (the green line takes you to the National Mall), but as of Oct 2023 the bridge is out due to a storm, and by the looks of it it’s been out a while and it doesn’t appear that it will be fixed soon. So what we did, since we don’t have a tow car, and just have our 26ft motorhome, is we packed up and drove to the Greenbelt station about 5 miles away, parked there for the day, and took the green line into town. The lot there is huge and open and free on weekends. Weekdays it’s about $5/day if you take the metro, and about $9 if you’re just parking there. The College Park station is closer but is apparently a parking garage (can’t confirm because we didn’t go to that station). This worked very well for us. You can pay for the metro with an app or get a card, either way it costs you $2 to buy the card, and then $2 each way on the train. Everyone over age 5 needs their own card, no sharing one card. The train ride from the Greenbelt station to the national mall is about 30 min. Get off at the Archives station to be in the center of all the sites.
