We had to go pretty far back to get a spot, because everyone was there. You do have to pack your trash back out, but there are two dump sites as you are leaving as well as a septic dump. 

I went during the pandemic so the bathrooms were closed and the dumpsters were very full. But stop at the vistas coming in and going out, they have great trails and great views. 

Be careful on the dirt roads though, there is soft sand at the sides and you could easily lose traction and go off the road. There are little trails to awesome hidden gems where no one would even know that you were there.
