You can buy a camping reservation to ensure entry.
I have always seen first come first serve. Still, seemed pretty empty when I went. Just go on a week day and you probably will be fine I bet.
There working on a ticket system that if you miss the morning opening,your spot is reserved for the evening opening.
As far as I know parking is first come first served. I do not know about if you are camping
You can reserve campsites on line and they have a parking space, but don't think you can only reserve parking.
You can reserve campsites. They told me that even if there is a line and you have reservations, the only option is to wait in line till you get to the front. If you go during the week or early on Friday there is not a line. We got there at 1p Friday and no line. We parked the car after setting up camp and did not move it till Sunday. Great place to camp and hike.
Yep..... allegedly ..you can go online
