The famous alley in San Francisco known for its slope is Lombard Street. Often referred to as the "crookedest street in the world," Lombard Street features eight sharp turns on a steep hillside, making it not only a unique part of the city’s landscape but also a popular tourist destination. The street's brick-walled, floral-lined curves are a picturesque sight, attracting visitors who come to walk or drive down the winding road. Lombard Street’s exceptional design and scenic views of the bay and city make it an iconic symbol of San Francisco.
