Ensenada, Baja California, Mexico
Seventy-five miles south of the U.S.-Mexico border, Baja's third-largest city is also its largest port. A rusted hull of an old tanker serves as a fascinating symbol of the port's history. Throngs of shopaholics seek bargains on onyx, local artisan works, and abalone. For the drinkers, many cantinas line the shopping district for some relaxing in the Mexican sunshine. If you want to explore the city, just walk a few blocks off the main shopping drag and you will be smack in the middle of tiny groceries, even tinier taco stands, and quiet, dusty streets. Also south, La Bufadora--a famously big blowhole--spurts up the sea with regularity.
