Camping inside the washington dc beltway
The Greenbelt campground is now $20 a night. There is no longer an iron ranger to pay, reservations ($10 one time fee) and payments must be made online.
May is one of my favorite months for Washington DC. I can't make it but maybe you can. This campground gets lost in the National Capital Parks-East properties, it's just 12 miles from the White House and only $16!
