North Pismo State Beach is a good campground right on the beach and next to a Monarch park. The bathrooms are clean and have showers. The showers take tokens which you can get from the machine next to the bathrooms. The sites are all drive thru. 

The campground is about a mile from downtown Pismo and is a great place to have lunch or dinner.  To the south is Pismo state beach where you can actually drive your car on the beach for $5. Can't beat that deal.

A bit crowded, but it's hard to beat camping right on the beach

Great place to camp right off the dune though can be crowded and has many spots that are not on the beach. The sites are not ocean view with the sand dunes but a short walk over and your there. Also a very easy walk on the beach to downtown. It can get crowded and their is a security booth where you have to sign in, little annoying when they tired to charge our two motorcycles as two cars but they let's us by.

Love beach camping. Go here every year for Thanksgiving. Beautiful place. Lots of dunes to ride and fun times ocean fishing
