Darband Sar, located 45 km east of Tehran, Iran, and a 2-hour trip from the Caspian Sea, is a region known for its temperate climate and high altitude of about 3125 m above sea level. Annexed to the city of Shemshak in 2012, it is now part of Shemshak-Darbandsar. The area boasts a cool and pleasant climate during warm seasons and low humidity similar to Tehran. Its ecosystem offers unique opportunities for eco-tourism and recreational activities, including three nearby ski resorts, Boomak, and the Tartangeh waterfall. The proximity to Tehran makes it an accessible destination for a short trip to this mountainous countryside.
