"Haft Kul" or "Seven Lakes" is the name of cascading lakes among the Fan Mountains in the northwestern part of Tajikistan, near the city of Penjikent. A group of mountain lakes amaze visitors with their bright and constantly changing colors. Each lake has its own name: the lowest lake, which travelers usually meet first, is called Mizhgon. Next are Soy, Khushor, Nofin, Khurdak, Marguzor (the largest) and Hazorchashma (the highest).
Seven lakes are in the Fan Mountains, in the gorge of the Shing River. Ancient petroglyphs discovered on the shore of one of the lakes indicate that the lakes are quite old. The lowest lake (Mizhgon) is located at an altitude of 1,640 meters, and the highest (Hazorchashma) is 2,400 meters. The height difference between the lowest and highest lakes is 760 meters, and the distance between them is more than 14 km.
