Cartago generally offers a safe environment for solo female travelers. Like many places, it maintains a sense of safety during the day, especially in high-traffic areas where locals and other travelers frequent. Local residents are usually friendly and willing to assist if needed. However, it is always important to exercise common safety measures such as avoiding deserted areas after dark, keeping personal belongings in secure locations, and maintaining a certain level of awareness of surroundings. In general, while the city is secure, it's still crucial to remain vigilant.
