Sarpoosh Tangeh Valley

Sarpoosh Tangeh Valley is one of the most remarkable natural valleys near the city of Chalus in Mazandaran Province. It lies along the Chalus Road, just past Marzanabad. The valley has formed within the dense Hyrcanian forests, and its narrow, corridor-like structure gives it a distinctive, mysterious atmosphere. Clear water flows between moss-covered rocks and cliffs beneath a thick canopy of tall trees, creating a landscape where forest, water and light come together in a rare, natural setting.

The area is known as an adventurous nature destination, and its route includes forest paths, small waterfalls and narrow gorges. In some sections the tree canopy is so dense that sunlight barely reaches the valley floor, creating a cool, semi-dark space. Plant species such as Persian ironwood (Parrotia persica), hornbeam and alder, together with the sound of running water and the presence of forest birds, make this area a lively and very scenic ecosystem. Natural waterfalls with small pools further add to the valley's visual and natural appeal.

Sarpoosh Tangeh can be reached via the Chalus Road and the Mohammadabad area after Marzanabad, and the final part of the route requires walking on forest trails. Crossing the first gorge is relatively easy, but the second gorge is a more difficult route that requires safety equipment and mountaineering experience. The best time to visit the valley is spring and summer, when the weather is more stable and the water flow is at its best. Following safety principles, going with a local guide and taking care to protect the area's pristine nature are essential for a safe and responsible experience.
