Fetch your luggage, exit the gates of San Luis Potosi, San Luis Potosi Airport (SLP-Ponciano Arriaga Intl.), and collect your rental car. Which one you hop into depends on where you’re venturing. If you’ll be primarily driving in downtown Soledad de Graciano Sánchez, around 6 miles from the terminal, select something zippy. A compact car with good maneuverability will be ideal for navigating those winding city streets. But with so many things to see, like the glorious caves of the region, you may want to add some pit stops. A bigger vehicle, like an SUV or a full-size car, will make longer road trips a joy.
