Pretty, sweet and relaxed but lively. That’s how I would describe the cathedral and park in San Luis Potosí.
The city itself is in the north of Mexico and is one of those places where you can see very clearly that the centre has been pimped up and made pretty for tourists, but there’s not too much apart from that. Like it’s that it’s ugly, it’s just that I found absolutely nothing cool to see or do outside the centre – even in my online research. That may also be though because most tourists come to the capital San Luis Potosí because of the surrounding nature of the state of San Luis Potosí. Which was also the case for me. Like shortly after I arrived I went straight on to Ciudad Valles, because from there you can get to some nice waterfalls. And on the way from another also touristy city you often have to stop in San Luis Potosí to get to Ciudad Valles. 
Yet the centre with the cathedral and the park is really beautiful and definitely worth a visit during the day and at sunset. There’s just not much else in San Luis Potosí.

Go or not? If you’re in San Luis Potosí, one hundred per cent. I mean, why would you want to miss out on the most beautiful thing about this little city? However, unless you want to take in the waterfalls on the way, I wouldn’t go to San Luis Potosí. It’s really cute, but other small cities – some of which are even smaller – simply have more to offer. Nevertheless, of course I don’t want to put anyone off 😊
