Calexico, like any location, requires a level of caution. While violent crime rates are relatively low compared to other U.S. cities, one must be careful of petty crime such as pickpocketing especially near the border areas. It's best to blend in with the locals and not display any ostentatious items. Public places, like shopping centers and parks, are generally safe during the day. Overall, staying cautious and practicing common travel safety procedures ensures a positive experience.
