Didn’t make it to our destination so had to improvise. This place allowed me to make an online reservation and complete check in the next morning. For $30 (roughly) we had access to a bathroom and a great clean camp site.

Edit to add: if there is a chance you will stay at another state park within a year get the adventure pass for $105. It comes with 3 free nights. I spent $62 on another camp site the next day.
