They do not have reservations open yet, I even called the park and spoke to them. It is an open around the year CG, so I assume in low demand season it is first come first served. I will surely try to land a good site once I am there.
Do you know of any good site numbers so I can ask for them when I am there ?
I was very leery of driving 9 hours and not finding a spot but they assured me that they only get around 10 or 15 campers around easter. Fingers crossed
