Is this campground open for the 2020 season as of 6/9/2020? We drove through & it seemed there were plenty of campers there. On the website it said "unavailable" and isn't advertised as open. Of course nobody to call.

Yes. Jumbo campground is open for first come first serve. Reservations dont start until June 26th in that campground that's why its showing unavailable on recreation.gov. You can call 928-537-8888 for more information. Unlike the reservation company, we are answering calls. We are the concessionaire that manages that campground.

If it's the same ones we went to then ya we camped there over the weekend
