The only guide dedicated entirely to hiking San Franciscos East Bay has been revised and updated, and features 3 new trips in Contra Costa County. Includes 56 trips for hiking, bicycling, and horseback riding on oak-studded hills, grassy ridges, rocky peaks, forested valleys, and salt-marsh shoreline. East Bay Trails is the most complete and up-to-date trail guide for Alameda and Contra Costa Counties. While the route descriptions pertain to hiking most of all, other outdoor enthusiasts-fitness walkers, joggers, equestrians, and bicyclists-will also find them useful.
