The altitudes and mountains of central Alborz – especially in the border between Chalous and Haraz roads – are among the most important natural areas of the country. Due to the existence of Alborz Mountains, the northern part of the province has cold winters and cool summers, while its southern part has a warm and dry climate because of the geographical proximity to vast plains. The most known handicrafts of the province include painting on leather, glassblowing, glass engraving and painting, and wooden handicrafts.

The ancient pieces of evidence found in Uzbeki Hill in Nazar Abad county show that the history of Alborz province dates back to more than six thousand years ago with also more recent cultural remains referring to the Median Empire (678-549 B.C.).

Empires have also been found around Karaj, indicating that civilization has been continued in the region for a long period of time.
