No... you don't have to have a reservation... but most sites are reserved! They do get cancellations and they start offering them after 9:00 am.
U don have to have a res, but they are always booked up u have to do like 6 month ahead to have some kind of choice reservecalifornia.
Make a reservation.
You have to have reservation.
I would call to see if there space, its good to reserve a spot
During summertime its 95-100% full, reservation books preaty quickly here but possible. Its tent & RV spaces
You definitely need a reservation, 4 months in advance if you plan to go during the summer / the busy season. In the off season you can sometimes get a site a few weeks in advance. It is not first come first serve.
Reservations. I would recommend you make reservations 4 months in advance
