Botan Valley National Park
Set within the boundaries of Siirt province, Botan Valley (Botan Vadisi) is the deep valley formed by the western-flowing Botan River (Botan Nehri), which takes its source from the foothills of the high mountains in the south of Bitlis. Botan Valley, one of the steepest and deepest valleys in Türkiye, extends towards Siirt in the south. Starting from the mountains to the south of Bitlis province in the west, the Botan Valley passes between the 2,741-meter-high Doğruyol and the 2,631-meter-high Mount Kapılı and goes into the Tigris Valley during its trip to south towards Siirt. Remains of human civilizations from the Neolithic Era were found in the Botan Valley, which was later the site of the “Anabasisi (The Ten Thousand)”, written by Xenefon in 407 BCE Historical roads and some parts of the ancient Silk Road can still be seen in the area. Many of these roads date from the era of the Assyrian Trade Colonies and were built as stone-paved roads, depending on the topography; some of these roads were repaired and continued to be used during the Roman Period.
