The worst places to live in Mexico are probably places where the crime rate is the highest or the murder rate is the highest. They is really no reason to go to a place like that unless you have family or a specific reason to go there.
Some people have an idea of what they want Mexico to be in their heads. So if you’re looking for palm trees and white sand beaches and crystal clear water like you’d find in the Yucatan Peninsula, the worst place to go would be Tijuana or Rosarito, because Tijuana is crowded, it’s the border town, the water is cold, and the beaches are a little bit barren. It’s the same in Rosarito—it’s cold, it’s very spread out, it’s got rocky beaches, and it’s completely different from, for example, Cancun. So the worst place to go would be somewhere that doesn’t align with your expectations.
Some people hate the hot weather and they wouldn’t be caught dead in the Yucatan Peninsula but they would love it in Northern Baja, where the temperature and climate is the same as California. So it just depends on If you’re looking for a beach town and a laid-back lifestyle like Puerto Vallarta don’t move to Mexico City and vice versa. If you’re looking for a cosmopolitan city living don’t move to a beach town in the middle of nowhere.
