During my recent stop over at the local office of the Automobile Club of Southern California, along with the two Woodall's campground directories, I also picked up some maps of Public Lands Campgrounds, one for Northern California and one for Southern & Central California.
These maps show the location of different campgrounds available for public use administered by the National Park Service, California State Parks, U.S. Forest Service, County Departments, California Department of Forestry and Fire Protection, Bureau of Land Management, U.S. Army Corps of Engineers and City Departments and Special Districts.
The maps contain information such as telephone numbers, elevation, months open, basic nightly camping fee (if any), reservations, designated tent sites, designated RV spaces, the number of tent/RV spaces, hookups (if any) for water, electric & sewer, drinking water availability, toilets (flush or other), showers, barbeques/fire rings, tables and if wheelchair accessible.
Camping in a public lands campground is a great alternative to private/commercial campgrounds. Sometimes, private campgrounds may be full or too pricey, so having a guide to public lands campgrounds would come in handy to see if there are any available in the area you're in.
These maps are offered free of charge to Auto Club members.
