Each area is unique, with regions that are mostly covered in sprawling suburbs and cities to the wine country and nature areas to the north.

The topography and landscapes that make up the regions of the Bay Area vary greatly, along with their unique major cities.

San Francisco

🏢 BIGGEST CITY: San Francisco

San Francisco is not only a city but also a county and a region of the Bay Area. 

This metropolitan city is one of the top tourist destinations in the world for its incredible landmarks and attractions, including the Golden Gate Bridge and the Coit Tower.

The North Bay is the largest of the regions in the Bay Area, with double the land mass of the second-largest area.

This special region is best known for the Napa and Sonoma wine-growing areas that draw in millions of tourists annually to taste and explore the vineyards.

A big draw to the North Bay is its easy access to outdoor recreation in the Marin Headlands and the Point Reyes National Seashore for great beaches, hiking, and the coastal redwoods.

One of the most popular destinations in the Bay Area for tourists is the Golden Gate National Recreation Area, which offers spectacular views of the city and the bridge.

East Bay

🏢 BIGGEST CITY: Oakland

The East Bay is the largest region in terms of population and second in overall square miles, and stretches from the shore of the bay to the San Joaquin Valley.

Outside the urban hubs like Oakland and Berkeley along the bay, the vast majority of this region comprises affluent suburbs that serve as commuter cities.

This region is a cultural icon based on its history of protests and progressive politics and a music scene that spans many genres ranging from jazz to punk rock. 

In the heart of the East Bay, you will find the campus of UC Berkeley, which is a leader in Social Sciences, Engineering, and Biological Sciences.

This smaller region only covers 448 square miles and is home to three-quarters of a million people. 

On the coastal side of the region is the famous jump-off point for trips down Highway 1 on the Pacific Coast Highway. 

This area south of San Francisco is a popular spot for visiting the beaches in Half Moon Bay and for catching some waves at Mavericks or at the beaches in Pacifica.

Most trips to the Bay Area start in the Peninsula region, which is the home of San Francisco International Airport.
