Greenbelt Campground is reserved through Recreation.gov, on the release pattern stated in its official listing. In demand, reservable sites are claimed within minutes of each release — which is why the campground reads as sold out for most of the year, and why the realistic route in is rarely the release itself.
Sites booked months ahead get cancelled as trips fall through, and each cancellation returns its nights to the official calendar instantly — first-come, no waitlist, no announcement. itOpened scans the Recreation.gov calendar for Greenbelt Campground around the clock; when a site matching your dates and vehicle opens, you get a text with a direct link, and you book it yourself, in your own account, at the normal price. We never book, hold, or resell. The mechanics are the same ones documented in how campsite cancellations actually work.
