Self Check-in when the office is closed

Oregon SP make use of self registration during the fall, winter, and spring at many parks. Some parks have a non reservation loop where you can take a spot for as many as 14 days. In the reservation loops, if not reserved for that night you can have it for that night. This allows rangers to work on winter maintenance projects rather than sit in a booth waiting to check in campers. If you use Reserve America, about two weeks before your arrival you will receive an email with a link to a document that serves as your window hang tag.
The SRE (Self Registration Envelope) allows the use of Cash, check, or Credit Card.
