Acho Darreh

Acho Darreh is one of the scenic natural and mountain attractions of Mazandaran Province, in Sari County, Dodangeh District. It lies south of the city of Sari, near the Shahid Rajaee Dam (Soleyman Tangeh). The valley is known for its lush Hyrcanian forests, rivers, clear streams and mountain views, and it is an appealing, little-known destination for nature lovers and anyone looking for a trip outside the city. Its landscape combines forested slopes, trekking routes and small watercourses, making it a deep immersion in the unique nature of Mazandaran.

Acho Darreh can be explored on forest and mountain footpaths, and it is known among people familiar with nature-tourism routes. The trails usually start from the area around the Soleyman Tangeh Dam and the villages of Dodangeh District. After passing through Hyrcanian forests and gently sloping highlands, they reach the deeper parts of the valley. These routes suit travellers of average fitness, and they take hikers through forest scenery, past small rivers, and into the region's wildlife. Along the trails, the heights around the valley reach about 2,300 feet (about 700 metres), offering wide views over the surrounding area.

To reach Acho Darreh, start from the city of Sari and drive to Dodangeh District and the Soleyman Tangeh area. You can go by car to near the start of the valley, but the rest of the route through the valley is on foot. The best time to visit is spring and summer, when the forests are green, the weather is pleasant and the streams run clearer. Autumn also has its own charm, with its fall colours. Responsible nature-tourism practices, such as not leaving litter, staying on the footpaths and protecting wildlife, are essential to preserve this valuable area.
