Much of Iran’s terrain is mountainous. The Alborz and Zagros Mountain ranges in the north and western Iran, and the two deserts of Markazi and Lut have filled Iran’s heart. The deserts of Iran are less inhabited, and most of the population lives in the basins, plateaus, and plains. By having dense rain forests in the north, warm sunny beaches in the south, snowy mountains in the west, and scorching deserts in the east, Iran is one of the few countries that gives the joy of experiencing four different seasons at the same time to travelers. Iran nature is a safe haven for many endangered species. Among them are the Persian leopard, black bear, and Fallow deer. Asiatic Cheetah, also known as the Iranian Cheetah, is the world’s fastest land animal, and the last few are known to survive mostly in Iran.
