Guanajuato City is one of Mexico’s most spectacular – a UNESCO World Heritage maze of brightly painted houses climbing steep hillsides, narrow alleys called callejones, and a network of underground stone tunnels that double as roads. It is a stunning place to visit and a uniquely tricky place to drive, so a little preparation goes a long way.
Those famous tunnels
Guanajuato was built in a narrow ravine, and old flood tunnels under the city were long ago turned into roads. Driving through them is an experience – dim, winding, and disorienting, with exits that pop you out onto unexpected hillside streets. GPS often loses signal underground. The trick: drive slowly, follow the painted signs, and do not panic if you miss a turn – loop around and try again.
Park and explore on foot
The historic center is steep, cobbled, and not built for cars. The smart move is to park in a garage or lot on the edge of the center and explore on foot – the callejones, the Diego Rivera house, the Juarez Theater, and the funicular up to the Pipila monument are all best seen walking. Save the driving for getting in and out.
Getting there
Guanajuato pairs naturally with San Miguel de Allende and Queretaro on a Bajio loop, and connects by toll road toward Guadalajara and the Pacific. The highways between the Bajio cities are good cuotas – drive them in daylight and keep pesos for tolls.
Permits and insurance
Driving the central highlands is mainland Mexico, so carry your full TIP, FMM, and Mexican auto insurance throughout. A policy from an authorized insurer is inexpensive and required by law – buy it online before you go and review the documents checklist.

Frequently asked questions
Is it hard to drive in Guanajuato City?
It is challenging. The city’s underground tunnels replace many surface streets, GPS often fails down there, and the historic center is steep and cobbled. Drive slowly, follow the signs, and park on the edge to explore on foot.
What are the Guanajuato tunnels?
They are former flood tunnels beneath the city that were converted into roads. They carry much of Guanajuato’s traffic underground and are a famous, if disorienting, part of driving there.
How far is Guanajuato from San Miguel de Allende?
About 1.5 hours by car across the Bajio. The two cities, along with Queretaro, make a natural central-highlands loop.
Do I need Mexican insurance to drive to Guanajuato?
Yes. It is mainland Mexico, so you need Mexican auto insurance, an FMM, and a full vehicle import permit – the same documents required across the country.
