Scroll down the link and you will find a town map. The camps are marked as "Trailer" Parks.
Camps exist on the bluffs above the beach North of town, centered around Pete's and El Dorado, and more exist adjacent to Hotels that wrap around the bay to the South. These sites require a ten to thirty minute drive into town.
More quiet primitive (self-sufficient) camping is found South of town from Laguna Percibu and further away from SF.
