The Kumgang Mountains, often called the Diamond Mountains, are located in the Kangwon Province of North Korea and represent one of the most significant natural landmarks on the Korean Peninsula. Stretching over 160,000 square kilometers, the range is divided into Inner, Outer, and Sea Kumgang, each offering distinct geological features. The highest peak is Birobong, reaching an elevation of 1,638 meters above sea level. For centuries, these mountains have been a center of Korean Buddhism, hosting numerous temples like Pyohunsa, which dates back to the 7th century. The geological composition primarily consists of granite and diorite, which have been eroded into thousands of jagged peaks and deep ravines over millions of years. Between 1998 and 2008, the area was part of a special tourist region that allowed South Korean visitors to explore the scenic trails under strict supervision. Today, the mountains remain a symbol of national pride and a primary destination for domestic tourism and international mountaineering expeditions.
