The Baja run — Tijuana or Mexicali down Highway 1, through wine country, the mid-peninsula desert, whale lagoons, Loreto, La Paz, and finally Cabo — is the classic Mexico road trip, and bureaucratically it is also the easiest one. This guide covers the paperwork (there is less than you think), the insurance (there is more to it than you think), and the driving habits the peninsula rewards.
The paperwork: shorter list than the mainland
The whole peninsula — both Baja states — is exempt from the Temporary Import Permit that mainland Mexico requires for foreign-plated cars. No TIP, no deposit, no Banjercito line. What you do need: passport, an FMM tourist permit (at the border or online), your vehicle registration, and Mexican auto insurance. That last one is not optional in any practical sense: your US or Canadian liability coverage is not valid in Mexico, and an at-fault accident without Mexican liability can mean an impounded car and a very long day.
The insurance: price it per day or per season
A tourist policy at Timi is issued by Chubb, bought in an online chat, and starts around $12 USD for one day. Weekend in Rosarito or Ensenada: buy exactly the days you need. Chasing the Baja 1000 in November: same policy, race-week length. Wintering in Loreto or La Paz: 90/180/365-day plans exist for snowbirds, and trips over 30 consecutive days without leaving would need the extended-stay tier — the chat sorts that out from your dates. One policy covers the entire peninsula and all of Mexico; the destination never changes the territory.
The driving: three peninsula-specific habits
Fuel discipline. The famous gap is the mid-peninsula: after El Rosario, treat every real Pemex as the last one until the Guerrero Negro area. Half a tank is your empty light down there.
Daylight on Highway 1. Long stretches are one lane each way with no shoulder — fine at noon, unpleasant at dusk when the cattle wander. Plan the legs so highway time ends before dark; the peninsula's distances make this easy if you decide it in advance.
Cash pesos for the cuota. The Tijuana–Ensenada toll road (the scenic, patrolled way down) charges per booth and not all take cards. Checkpoints along the route are military and routine: window down, one minute, wave through — keep documents where you can reach them.
If the trip continues past Baja
Crossing by ferry from La Paz to the mainland changes the paperwork: the mainland does require the TIP, and our TIP guide covers it. The insurance, though, is already handled — the same policy covers both sides of the ferry.
