Great location and low price. We used the first-come-first-served camping option in May. There were still a couple open spots available during the week, but many of them were more a wetland than a camping spot. The information how to claim and how to pay a camping spot is very confusing at the kiosk, especially because there were several contradicting posters hanging around. You need a phone and data to pay for the site and you need to use the national parks app.
