Getting Around
San Diego's Metropolitan Transit System runs trolley and bus lines connecting downtown, Old Town, Mission Valley, and the border. For La Jolla, Coronado, and coastal areas, rideshare services or a rental car offer significantly more flexibility and save considerable time.
⚖️
Cash or Card
San Diego is almost entirely card-friendly, with contactless payment accepted at most restaurants, shops, and attractions throughout the city. Cash is useful for street tacos, farmers markets, parking meters in older neighborhoods, and tipping service workers who may prefer it.

Good to Know
San Diegans are genuinely laid-back, and that ease extends to dress codes, timelines, and social formality across most of the city. Showing up slightly late to a casual dinner is not considered rude, but cutting in line at a popular taco stand or surf spot will earn a notably cool reception.
🏧
ATMs
ATMs are plentiful across San Diego at banks, convenience stores, hotels, and shopping centers, with no shortage of options in tourist-heavy areas like the Gaslamp Quarter and near the waterfront. International visitors should check with their home bank regarding foreign transaction fees, as charges vary widely and can add up over a longer stay.
💳
Currency
The United States Dollar (USD) is the sole currency used throughout San Diego, accepted universally in every form from cash to digital wallets. Along the border corridor near Tijuana, some vendors accept Mexican pesos, but USD is always the practical default on the San Diego side.
🔌
Plugs
Type A and B outlets, 120V at 60Hz. Standard US plugs are used throughout. Most international visitors will need a voltage converter as well as a plug adapter.
🛡️
Safety
San Diego is one of the safer large cities in the United States, with most tourist areas feeling calm and well-patrolled throughout the day and evening. The downtown Gaslamp Quarter and areas near certain transit hubs can attract street activity late at night, so standard urban awareness applies after midnight.
✈️
Airports
San Diego International Airport (SAN), also known as Lindbergh Field, sits just two miles from downtown and is one of the most conveniently located major airports in the country. A taxi, rideshare, or airport shuttle delivers travelers to the Gaslamp Quarter in under ten minutes on a clear day.
