🚶 Walking Across the Border to Mexico
The most popular and budget-friendly way to reach Tijuana, Mexico from San Diego is by walking across the San Ysidro Port of Entry, one of the busiest land crossings in the world. You can take the San Diego Trolley Blue Line directly to the border, then cross on foot in 15–30 minutes. Once in Tijuana, taxis, rideshares, and colectivos make it easy to continue to your destination.
🚗 Driving to Mexico from San Diego
If you prefer driving, you can cross into Mexico via the San Ysidro, Otay Mesa, or Tecate border crossings. Driving into Tijuana takes about 30 minutes, depending on traffic. Make sure to carry a valid passport, Mexican auto insurance, and vehicle permits if traveling farther south. Driving gives you flexibility to explore Baja California’s beaches, Valle de Guadalupe wine region, and Ensenada.
🚉 Taking the Trolley & Bus Combination
Public transit is another cost-effective option. From downtown San Diego, board the Blue Line Trolley to San Ysidro. Once you cross the border, you can hop on ADO or ABC buses to destinations like Rosarito, Ensenada, and Mexicali. This option is perfect for those who don’t want to deal with border parking or driving in Mexico.
