KOA

I can't speak too highly of the KOA (Kampgrounds of America) organisation.  During our recent camping trip we stayed in about four of these places and found them to be excellent.  We had a book which gave all the various campsites in California and it was very useful, but after about four days, we just went for the KOA sites.  They are no doubt franchised as the set ups seem to be about the same with good individual sites, often a swimming pool and spa, a small shop that sells items you may have forgotten, and above all good bathrooms.  If you're a "primitive" type camper they may be a little too well organised but after several hours in the saddle they are first rate.
