The guide could really come in handy for finding quick alternatives when you arrive at your favorite “first come, first served” public campground and find it full up. It breaks up the state into 12 regions, from the North Coast to San Diego and eastern deserts.
Regional and individual park maps, events and highlights in the area, and details (important things like price, number of electrical hookups, whether tents are allowed, etc.) also are included. There are three ways to get the guide: download it from the website, download it from iTunes or Google Play on your mobile device, or request or pick up a print copy.
