Overview

Positioned at the southwestern corner of California in the United States right where the Pacific Ocean meets the Mexican border, San Diego unfolds as a collection of distinct coastal villages, mesa-top neighborhoods, and sheltered bays linked by canyons and ocean bluffs. Start with our San Diego overview and top things to do to organize your days by geographic cluster.

Crescent-shaped San Diego Bay is sheltered from open ocean swells by Cabrillo National Monument and Point Loma and the sandy peninsula of Coronado Island. Along the mainland bayfront sit the Embarcadero and Seaport Village, the USS Midway Museum, the Maritime Museum of San Diego, the Victorian blocks of the Gaslamp Quarter, Petco Park and East Village, and Little Italy. Directly northeast rises the twelve-hundred-acre cultural plateau of Balboa Park and the San Diego Zoo.

Getting there

San Diego International Airport (SAN) sits just three miles northwest of downtown on the bayfront, served by the free San Diego Flyer electric shuttle to Old Town Transit Center and MTS Bus Route 992 to Santa Fe Depot. Travellers from Los Angeles can ride the coastal Amtrak Pacific Surfliner train straight into downtown, while airline passengers flying into Tijuana can walk across the enclosed Cross Border Xpress (CBX) skybridge. Read our full arrival breakdown and getting around San Diego transit network overview.

Where to stay

Choosing the right neighborhood base prevents unnecessary highway driving. Little Italy and the Embarcadero offer walkable bayfront dining and trolley access, the Gaslamp Quarter puts you in the center of evening nightlife, Coronado suits relaxed beach resort stays, and La Jolla or Pacific Beach place you right on the ocean bluffs.
