David there are 2 NF campgrounds along Hwy 1 south of Big Sur.Kirk Creek overlooking the ocean,
and Plaskett Creek about 5 miles further south.
Also the San Simeon campground (Washburn) is a nice spot.
Up on the hill about a 1/2 mile from the ocean.You can hear the surf from your campsite.
Montana del Ore SP a few miles south of Morro Bay is a small camp on the cliffs above the ocean.
There is another NF site on Hwy 41 east of Morro Bay,Cerro Acto small seemed like a quite spot
back in 2010 as I drove through. Also the Morro Strand beach by the "rock. Just a gravel parking area on the ocean.
There is the Veterans campground in Monterey above the city hall and Colton Hall ,take Jefferson st.uphill and it comes to the cg.
Have fun.
