Oakland, across San Francisco Bay from its better-known neighbor, has its own claims to fame. Where else can you tour a fortune-cookie factory and take the Black Panther Legacy Tour in the same morning? Other choices include hiking in the hills, dining in Chinatown, relaxing in a park and visiting historic homes. For a nighttime diversion, cheer for one of three pro sports teams or head to Jack London Square, where there's a saloon the author frequented and Yoshi's, a renowned jazz club.
