I bought this guide, plusMoon Northern California Camping: The Complete Guide to Tent and RV Camping (Moon Outdoors)andFoghorn Outdoors California Hiking: The Complete Guide to More Than 1,000 Hikes (Foghorn Outdoors). I like that it specializes in No. Calif. I wish it were a little more opinionated and would highlight the MUST-SEE attractions, e.g., see this/don't bother with that/that's a MUST-SEE/that's a little hokey. But overall, it's a good companion to the other two books above.
