Popular campgrounds sell out the minute reservations open. How Recreation.gov booking windows work, how to prepare, and how to find sites when everything looks full.
Popular campgrounds in national parks and forests can book up within minutes of opening. If you've ever logged on to find everything gone, here's how to give yourself a better shot.
Recreation.gov handles reservations for many federal campgrounds: national parks, national forests, Army Corps of Engineers lakes and more. Many campsites open on a rolling window, often six months ahead, at a set time of day. But it varies: some open sooner, some later, and some parks release sites in blocks. Check the specific campground's page for its exact booking window and time zone.
After Labor Day, crowds drop, sites open up, and many campgrounds are at their most beautiful. Some close for the season in mid-fall, so check dates.
Cancel early if your plans change so someone else gets the site, and follow the campground's rules on quiet hours, fires and food storage.
Once you've booked, get your sleep system ready: staying warm when nights drop below 40.
