We spent a few weeks in that area a year ago last January. Anyone that visits that part of California should tour the Point San Louis Lighthouse. It's the last Victorian lighthouse. So nicely restored it looks like the cover of a story book.
We stayed a week at El Charro county park between Moro Bay and SLO. Nice quiet park, not crowded that time of year. Reasonable rate by California standards. Very convenient for visiting the coast or inland around SLO. We stayed another three or four nights at an RV park right next to the beach in Pismo Beach. Both of our bicycles were stolen while were there so it's not my favorite place.
