Dah-Tangeh Waterfall

Dah-Tangeh Waterfall, also known as Chehel Pelleh ("Forty Steps"), is located in Rudbar-e Qasran District of Shemiranat County, Tehran Province, in the area of Ahar village and Dah-Tangeh. The area lies in the central Alborz and is considered one of the capital's popular summer pastures. Dah-Tangeh is an uninhabited area with seasonal fruit orchards, such as cherry, sour cherry and walnut, and there are cool natural shelters nearby for visitors.

Chehel Pelleh Waterfall is a seasonal waterfall with a natural staircase-like structure, with a total height of about 50 metres. Parts of its course slide down over the rocks like steps, and at the end the water pours down in a short but eye-catching drop. The vegetation along the route includes fruit trees (plane, walnut) and medicinal plants such as rhubarb, thyme and pennyroyal. In spring these plants adorn the trail with their lovely colours and fragrance. The full-flowing river along the route, with its pleasant sound, also doubles the sense of calm.

To get there, head from Tehran towards Lashgarak Road, then Fasham, Oushan and finally Ahar village. You can drive as far as Ahar Square; after that you need to cover about 5 kilometres of mountain trail on foot or by light vehicle to reach Dah-Tangeh and the waterfall. The trail is fairly flat and suitable for easy walking. The best times to visit are spring (Ordibehesht) and autumn (Aban), when the trail is full of flowers and the weather is cool. When exploring nature, we recommend that you do not litter, protect plants and soil, and do not forget safety precautions (especially when crossing bridges and rocky sections), so that your trip is responsible and environmentally friendly.
