I’ll be honest, there’s never going to be a safe place that’s perfect in a apocalypse. No matter how many times I’ve tried to find a place that sounds perfect there’s always going to be problems with it. So keep in mind that the places I list aren’t going to be absolutely prefect and it really depends on many factors. Such as where it’s located, the type of zombies you’re dealing with, the skills you need in order to survive in such a location, the unpredictable weather/mother nature and if it hasn’t already been taken over by zombies (or other survivors – who may or may not be nice).
In no particular order these places are ideal for survival, some of them are even great for long-term survival. But the key for them being good places is how isolated they are, how self-sustain they are might be and if they have a strong structure and walls for any possible attacks.
