At the end of Rettilon road, if you go to the left it’s free, go right you need a $10 permit for the year. Not prorated. I just spent a month on the permit side and I couldn’t see much difference in the surroundings. Although it was off season. I don’t know about the busy season. There are portapottys at the entrance of the beach. They say there’s not but I just left there 3 weeks ago and they do have them. Enjoy!

If you have the permit - you’re good anywhere on the beach. And when we camped there, they did indeed drive around and check vehicles for the sticker/permit.
