They are quite booked up during the summer. Campers make reservations. I wouldnt just go there thinking there might be a spot available. Take the time to make reservations & there's a good chance You may not even get that! Sorry!
Check with the campground, but my experience at others is you can stay up to some limit subject to prior commitments. For example, Mazama Campground at Crater Lake NP has a 2 week limit.
Just book in advance if possible. I could stay one night only since it was fully booked for the weekend.
The spots are reserved. If you get there you can reserve a spot for however long or until someone else's reservation comes. They will let you know when you book it.
Sorry have no clue we booked it for 5 days
