History of Doi Khun Tan National Park
Established in 1975 as Thailand's 10th national park. The park is historically associated with the construction of the Khun Tan Tunnel between 1907 and 1918 during the reign of King Rama VI, engineered by German engineer Emil Eisenhofer, which was Thailand's longest railway tunnel and enabled the northern railway line between Bangkok and Chiang Mai.
Culture & Context
The park preserves the railway heritage of the Khun Tan Tunnel and station, which remain important symbols of early 20th-century engineering in northern Thailand and are visited for their historical and scenic value.
