It is open, you can check in any time. The road is blocked off and manned so if you have reservations you can get in any time. I just left last week.
It's closed due to last Years Forrest fire. I'd call to see if its open yet 2 weeks ago it was not but web site said it was
Gate "closes" at 10pm but if you dont want to piss off Dorrie the camp host from hell then you better be there before dusk.
