The San Francisco Peninsula is a landform located in California, bordered by the Pacific Ocean to the west and San Francisco Bay to the east. It is home to the city of San Francisco, known for its iconic landmarks like the Golden Gate Bridge and Alcatraz Island. The peninsula extends southward, connecting to the Bay Area and includes several other cities, such as Daly City and South San Francisco. Geographically, the peninsula is characterized by its hilly terrain and diverse ecosystems, including coastal scrub and urban areas. It plays a significant role in the region's climate, often experiencing fog and cool temperatures due to its proximity to the ocean. The area is also a hub for technology and innovation, with many companies located nearby in Silicon Valley.
