We had such a wonderful time staying 3 nights at Cerro Alto campground. Most sites are spaced for privacy. Very quite & peaceful. Easy access to hiking trails (Cerro Alto summit) from campsite. About a 20 min drive to Morro Bay/ Morro Rock. Pit toilets. No showers.
Only issue we encountered was that campground water source was contaminated and therefore shut off. Luckily we brought plenty with us and we're able to refill in Morro Bay. Check website about water situation or bring in own supply.
