San Luis Potosi has lots on offer. You could chill out for a good while in this place and not run out of things to do. If you want to soak up as much as you can in this energetic metropolis, you’ll need a rental car. Keep in mind that driving in big cities often comes with tight streets and even tighter parking spots. Don’t worry though, because a compact or mini car will make this much easier to manage. If you’re going to head straight out of the city and cruise around some of the caves that San Luis Potosi is well known for, you’ll probably prefer something with more cargo space. A full-size or mid-size SUV will make that longer drive comfortable.
