To visit Tijuana from the USA, there are several transportation options available, with the two primary modes being by car or by plane.

By Car:

If you choose to drive to Tijuana, you can cross the border by car through the San Ysidro Port of Entry, which is the busiest land border crossing in the world. Make sure you have your passport or appropriate identification, car registration, and any required insurance documents. The drive from major cities like San Diego, Los Angeles, or Phoenix can vary in duration depending on the traffic and your starting point.

By Plane:

Another option is to fly into Tijuana International Airport (TIJ) which offers domestic and international flights. From various airports in the USA, you can find direct flights to Tijuana. Once you arrive at the airport, you can take a taxi, shuttle, or rental car to reach your destination within Tijuana.

Whichever mode of transportation you choose, it's essential to have your travel documents in order and be aware of any specific requirements for crossing the border. Travelers should stay informed about current border crossing regulations and any travel advisories before planning their trip to Tijuana.
