Depends on time of year. They do reservations and take walk-up but you need to call the office to get a better idea. They have mostly reserved camping
Stop at the visitor center and ask them about vacancies or see what you can find on reserve America for openings. This park is very popular during the camping season May thru September.
Just like a lot of campgrounds you take your chance if you don't have a reservation. It seems to be a pretty popular place during the summer months. We went in June and there was a few spots
