San Diego has a suprising amount of hiking opportunities. This short guide by Sean OBrien explores some of the easier walks in the Laguna Mountains and Cuyamuca State Park. None of the hikes exceed 5 miles in length, and most have gentle grades. Almost all the hikes listed here are suitable for small children. Strong hikers, by contrast, walk all the trails in this book in a weekend. One cant really argue with the selection of trails, but the layout of the book leaves something to be desired. I find maps more valuable than Aerial photographs, and occasionally OBrien outlines the trail with black dots, making it very hard to follow the route on his black and white photos. Still, this is a fine guide for family visits, and worth getting.
