San Ysidro
Open 24 hours, 7 days a week.
San Ysidro is the busiest land border crossing in the world, but that reputation is about the northbound queue back into the United States. Heading south into Tijuana is usually far quicker. And because the whole of Baja California is a vehicle Free Zone, most travelers driving into Baja do not need a temporary import permit (TIP) for their car. Your real priorities here are entering with a valid FMM tourist permit and active Mexican auto insurance, since your US or Canadian policy is not valid across the line.
What's where?
Marker positions are approximate — confirm exact locations on the day.
The main red-light/green-light customs inspection point right at the crossing; a red light means a quick vehicle inspection.
Vehicle import permits (TIP). You only need this if you are taking your vehicle beyond Baja to the Mexican mainland, for example by ferry. To drive anywhere in Baja itself you do not need a TIP.
Most Baja travelers can skip this. Cards and cash accepted; bring your passport and vehicle title.
Walk into this building to get your FMM tourist permit application processed and stamped.
Cash exchange right by the crossing. Rates are usually fine for small amounts; compare before changing a large sum.
Step by step, southbound
Stay in the general southbound traffic lanes. The Ready Lane and SENTRI lanes are for the northbound return into the US, not for entering Mexico.
Pass the line of parked commercial trucks on your right. Do not follow them; they use a separate commercial crossing.
Driving into Baja? You do not need a vehicle permit, since Baja is a Free Zone. But every traveler still needs an FMM tourist permit. If you did not get it online, follow signs to the INM office at El Chaparral, park briefly, and have it stamped.
Reach the traffic signal (semaforo) for customs. Green means drive on; red means pull over for a quick inspection. It is random, and most travelers get green.
You are through. Follow signs for your route into Tijuana or down the coast, and make sure your Mexican auto insurance is active before you drive any farther.
What travelers report
Southbound traffic is usually light. Early morning and mid-morning on weekdays move fastest.
Holiday weekends and Friday afternoons bring heavier southbound traffic and more frequent Mexican inspections.
