Lombard Street (Russian Hill) - advertised as 'the crookedest street in the world'

The one-block, eight-turn section of Lombard Street between Hyde and Leavenworth is widely promoted as "the crookedest street in the world" because of its tight hairpin turns on a steep slope. This designation is informal and promotional; other streets have also been called the crookedest, but Lombard's block is among the most famous examples globally and a documented tourist landmark. The crooked block is frequently cited in travel guides and municipal materials.
