Tang-e Nol

Tang-e Nol is one of the natural attractions of Dena in Kohgiluyeh and Boyer-Ahmad Province, located near the town of Sisakht. The gorge lies within the Dena Protected Area, on the road to the Cheshmeh Nol spring, where seasonal rivers flow out of the heart of Kuh-e Gol. With its wild scenery, high mountains, rocky cliffs and distinctive mountain landscapes, Tang-e Nol is a popular destination for nature lovers, canyoning enthusiasts and anyone who loves the silence of the mountains. The route through the gorge winds between rocks, trees and cool streams of water, giving visitors a delightful experience of being close to pure nature.

At the end of the gorge there is a limestone cave about 80 metres long with several chambers, including entrances up to five metres high and beautiful stalactites and stalagmites. Along the way, small pools of water have formed and springs well up from the ground. The route is lined with varied vegetation, including mountain shrubs, gon (astragalus), wild almond and wildflowers, as well as medicinal plants such as thyme, lavender (ostokhoddus) and chavili (chuyli). In spring it is at its most beautiful, with colourful blossoms.

To reach Tang-e Nol, head from Sisakht towards Kuh-e Gol. After about 20–25 minutes of mountain walking along a gently sloping path, you will arrive at the entrance to the gorge. The visit takes between 2 and 3 hours, and ordinary hiking gear is enough (suitable shoes, a water bottle or hydration pack, and warm clothing for the cool air inside the cave). The best time to visit Tang-e Nol is from mid-Farvardin to the end of Khordad (early April to late June), when the landscape is green, the waterfalls are full and the weather is mild and refreshing. At this time of year the area comes alive, and visitors can capture unforgettable moments through walking, light water-based trekking and photography. Visitors should follow the principles of responsible nature tourism; in particular, do not leave litter and avoid damaging the limestone formations.
