Unfortunately, we don’t allow anyone on park property except during operating hours for safety reasons. Right now, the park is open 8:00 am - 5:00 pm, seven days a week. Beginning March 1, the park will be open seven days a week, 8:00 am - 7:00 pm. If you have any further questions, please don’t hesitate to ask.
I'd wait til they open
It is very dangerous. You sign your name at the entrance and the time you start the loop. That way if you don't show up the rangers can look for you. I recommend to be safe and wait till open
