San Francisco is one of the loveliest cities in the world. Walk the hilly streets and enjoy the stately Victorian houses with their million-dollar views. Check out the Golden Gate Bridge, have a burrito in the Mission, play Frisbee in one of the city's many graceful parks, ride a cable car and enjoy amazing views of the Pacific Ocean and San Francisco Bay. It's easy to see why Rudyard Kipling wrote: "San Francisco has only one drawback - 'tis hard to leave."
