San Diego reflects its Spanish-Mexican heritage in every corner; you won't forget that bustling Tijuana is just across the border, less than 30 minutes away. San Diego boasts one of the nation's priciest housing markets and a biotech/tourism/telecom economy that's firing on all burners. A full-fledged building boom is transforming formerly seedy downtown neighborhoods and architecturally rich suburbs into upscale wonders. And the stylish young residents and shop owners they attract are, in turn, updating and enriching San Diego's dining, shopping, and entertainment options.

Amid all the change, San Diego is still first and foremost a big outdoor playground. You can still swim, snorkel, windsurf, kayak, bicycle, in-line skate, and partake of other diversions in or near the water, as you like. And top-notch civic attractions still include three world-famous animal parks and Balboa Park, one of the finest urban parks in the country.

So pack a laid-back attitude along with your sandals and swimsuit. Prepare for a warm welcome to California's grown-up beach town.
