Large open sites. Big rigs go left and park on top. Large areas, can accommodate dozens of RVs and tents.
Avoid during holidays, people leave tents and rvs for days to keep the spot despite rules and the ranger station will do nothing about it. At those times expect loud parties and even fights or gunfire which the rangers will also do nothing about.
Other than that its great. Take a right on the highway and head to the sourdough lodge for the best pancakes for hundreds of miles.
There are many other dispersed and paid spots along the highway.
