San Luis Potosi has a mixed safety record. While the city center is generally safe during the day, there can be high levels of crime, particularly after dark and in more secluded areas. It is recommended to remain vigilant at all times and stay in high populated areas where possible. Utilizing registered taxis or trusted transportation apps, avoiding late-night outings, and not displaying wealth can significantly improve your safety. Local people are typically friendly and helpful to tourists; however, one must always keep their guard up. Solo female travelers should exercise common sense precautions, similar to those in other cities across the world.
