Mexico has diverse regions that are safe to explore, while others are highly dangerous. Highly touristy places like Cancun, Riviera Maya, and Mexico City are generally safe for solo female travelers. However, the unpredictable criminal activity and drug-related violence in certain regions could pose risks. Exercise common sense, stay vigilant about personal safety, avoid isolated areas, and always keep your belongings close to you. Also, ensure to respect local norms and culture. It's advisable to opt for organized tours or travel in a group while visiting lesser-known regions.
