The highest peaks in Mexico are located around Mexico City, where the volcano is located. Another area where you can find the higher peaks in Mexico are in Durango. There are regions here in Mexico that get snow. Most people do not believe that but there are winters here. There are areas, especially in the Sierra Madre, that are covered with snow during the winter. There are actually a couple of ski resorts in Mexico.
Even as you get closer and closer to the equator, if you go to the more mountainous regions, where you get some elevation in Mexico, you can get some mild temperatures. There are some very well-known expat communities in Chapala, in San Miguel Allende, and in Oaxaca, which are places that are located high up the mountains, where they get spring weather all year round. You can definitely get 75 degrees Fahrenheit all year round in these places.
