Tang-e Kalshakh

Tang-e Kalshakh is one of the pristine, technical canyons of Lorestan Province, located near the town of Dorud. With its long, narrow corridors, parts of the canyon become completely cave-like, and getting through it requires technical canyoneering skills and specialized equipment. Thanks to its distinctive geological structure and varied water flows, Tang-e Kalshakh has become a popular destination for experienced canyoneers.

Kalshakh Canyon has narrow passages, numerous waterfalls and powerful water currents. In the high-water season, especially until the middle of Khordad, the water volume in the canyon is high and the currents can be dangerous. The vegetation of the area includes species such as astragalus (gavan), wormwood (artemisia), soapwort (choobak), thyme and Kolah-e Mir Hassan, which reflect the area's biodiversity. The rocks of the canyon are red conglomerate, sandstone and siltstone, which add to its beauty and visual appeal.

To reach Tang-e Kalshakh, there are local routes from the town of Dorud toward the Dorud–Razestan area. The best time to visit the canyon is spring, especially the month of Ordibehesht, when nature is at its most beautiful and the canyon's water flows are at their most attractive. When visiting Tang-e Kalshakh, it is essential to follow the principles of responsible nature tourism, such as keeping the environment clean, not harming the plants and wildlife, and respecting local culture and traditions.
