With more than 40 hills in seven square miles, no wonder San Francisco is home to some of the most scenic stairway hikes in the world. Climb the Lyon/Broadway stairway to heaven and see why the Pacific Heights neighborhood is so named. Reward yourself at the end of this five-story ascension with vim, vigor, and a bird's eye view of prime real estate rooftops, the Palace of Fine Arts, Alcatraz, and the Golden Gate Bridge.
