The Khun Tan Range is a major mountain system in northern Thailand, stretching across the provinces of Lamphun, Lampang, and Chiang Mai. Geographically, it serves as a critical watershed dividing the drainage basins of the Ping and Wang rivers. The range is best known for the Doi Khun Tan National Park, which preserves a diverse array of forest types, ranging from highland pine forests to evergreen tropical jungles in the lower valleys. A notable engineering feat within this range is the Khun Tan Tunnel, Thailand's longest railway tunnel, which facilitates the main rail link between Bangkok and Chiang Mai. The geology of the range is characterized by granite and sedimentary rock, resulting in a rugged and varied topography. Historically, the region served as a sanctuary and strategic refuge during times of conflict. Today, it is a hub for ecotourism, popular for its extensive hiking trails, waterfalls, and the opportunity to study native northern flora across different altitudinal zones.
