Things to do while visiting San Francisco California.

No. 1 - Voted America's top city in numerous surveys, colorful and cosmopolitan San Francisco invariably charms visitors. Its 1.7-mile-long Golden Gate Bridge -- one of America's top ten construction marvels -- is a must-see. Celebrating its 65th anniversary, this graceful span (which connects to Marin county) is an unforgettable icon to drive, walk, or cycle across.

No. 2 - Contemplate your next move in Golden Gate Park. Within its thousand-plus acres are gardens, lakes, bridal and walking paths, Strybing Arboretum and Botanical Gardens, and the tranquil Japanese Tea Garden, originally part of the 1894 World's Fair Exhibit.

No. 3 - Named San Francisco's best museum, the Exploratorium is a fun, quirky museum of science, art, and human perception that features some 650 "please touch" exhibits. Its pitch-black Tactile Dome may inspire you to approach challenges in a whole new way.
