Best San Diego Travel Guide: Things to Do, Where to Stay & Tips


Getting There

San Diego International Airport (SAN) serves as Southern California’s primary gateway, located just 3 miles northwest of downtown making it one of America’s most conveniently positioned major airports. The airport offers non-stop flights to 87 destinations including 11 international destinations in 7 countries as of February 2026. Major international carriers include KLM (Amsterdam), British Airways (London Heathrow), Lufthansa (Munich), and Air France (Paris seasonal). Domestic flights connect San Diego to all major U.S. cities via Alaska, American, Delta, Southwest, and United. The airport is the busiest single-runway commercial airport in the United States, handling both international and transcontinental flights efficiently. Ground transportation from the airport includes MTS Route 992 bus to downtown (19 minutes, $2.50), ride-share services (Uber, Lyft), taxis, rental cars from all major agencies, and hotel shuttles. The airport sits just off I-5 and N. Harbor Drive for easy highway access. Amtrak’s Pacific Surfliner connects San Diego to Los Angeles, Santa Barbara, and San Luis Obispo along the scenic coast. Greyhound and Flixbus provide intercity bus service. Cruise ships dock at the B Street Cruise Terminal downtown. No visa required for U.S. citizens; international visitors should verify passport requirements.

Getting Around

San Diego’s MTS (Metropolitan Transit System) operates an efficient trolley network with three main lines connecting downtown to major attractions, beaches, and the Mexico border. The Blue Line runs from downtown to San Ysidro (Mexican border), the Orange Line connects East County to downtown, and the Green Line serves Old Town to Santee. All trolley lines now accept contactless payments – simply tap debit/credit card or mobile wallet with no tickets needed. The MTS bus system provides comprehensive coverage throughout the county. Day passes ($6) allow unlimited trolley and bus rides. Note: Orange Line weekend closures occur through November 2026 for improvement work, with free shuttle buses replacing service. Downtown San Diego is highly walkable, especially the Gaslamp Quarter, Little Italy, and Embarcadero waterfront. Ride-share services (Uber, Lyft) are abundant and reliable. Bike-share programs (HOPR, Lime) offer electric bikes and scooters throughout downtown and beach areas. Rental cars are recommended for exploring coastal communities (La Jolla, Coronado, Pacific Beach) and inland attractions (Safari Park, Legoland). The Coronado Ferry connects downtown to Coronado Island ($7 round-trip). Beach cruiser rentals are popular in coastal neighborhoods. Avoid driving in Gaslamp Quarter and Little Italy where parking is expensive and limited. Plan on $20-30 daily for downtown parking or use trolley from free park-and-ride lots.
