Koohrang Tunnel Waterfall

Koohrang Tunnel Waterfall is one of the most remarkable natural attractions of Chaharmahal and Bakhtiari Province. It lies near the town of Chelgerd, in Koohrang County. This distinctive waterfall is regarded as one of the main sources of the Karun and Zayandeh Rud, two of Iran's great rivers, and it plays an important role in supplying the region's water. The waterfall is fed by the outflow of the first Koohrang Tunnel, a historic tunnel built in 1332 (Solar Hijri) to carry the water of the Koohrang spring and the surrounding springs to the Zayandeh Rud. The tunnel and its outflow create a striking blend of nature and engineering in the heart of the Zagros.

The tunnel's powerful, year-round flow spills over in the form of a waterfall in a natural setting, surrounded by green pasture and natural gardens. The area around it is equipped with facilities such as gazebos, handicraft stalls, a car park and restrooms to make visiting more comfortable for tourists. Besides its natural beauty, the area has clean, pleasant mountain air that attracts many visitors in every season. The route to Koohrang Tunnel Waterfall is also fairly easy, so visitors can comfortably enjoy the unspoiled nature of this region.

To reach the waterfall, first enter Koohrang County (Chelgerd) and head toward the first Koohrang Tunnel. These places are reachable by a paved road and require no long walk. The best time to visit is from spring to summer, when the weather is pleasant and the green vegetation, together with the gentle sound of water, creates a delightful atmosphere. For responsible travel, we recommend stopping only in designated areas and not leaving any litter, so that the region's ecosystem is preserved.
