San Diego
San Diego pairs a laid-back, sun-soaked coastline with a naval and border-city heritage, from Balboa Park's museums and the historic Gaslamp Quarter to miles of Pacific beaches. Its mild year-round climate and proximity to Mexico give it a distinct binational, outdoorsy character rare among major US cities.

Frequently asked questions about San Diego
How do I get to San Diego?
Most travellers arrive via San Diego International Airport (SAN), just a few miles from downtown; since no trolley line reaches the terminals directly, the reliable route is the MTS bus (route 992) or free airport shuttle connecting to the Old Town Transit Center, from where the San Diego Trolley and Coaster/Amtrak trains fan out across the region. A taxi or rideshare to downtown takes only ~10-20 minutes depending on traffic.
How many days should I spend in San Diego?
Plan on ~3-4 days to cover downtown, Balboa Park, and the beaches, or a week or more if adding day trips to nearby coastal towns or across the border to Tijuana.
