Duijan Waterfall

Aghsu Waterfall in Duijan lies near the village of Dowgijan (Duijan) in Marand County, close to the city of New Bonab. It is one of the pristine, little-known natural attractions of northwest Iran. Thanks to its abundant water resources, fertile land and rich vegetation, the area has long been known as a green region well suited to farming. Aghsu Waterfall, about 7 kilometres from the village, is the area's most important natural feature. All year round, its clear, cold water creates a calming and pleasant view.

Around the area, a mountainous landscape of springs, valleys and rocky paths offers a wide variety of natural attractions. Near the mountaintop there is a natural limestone cave. Its total darkness and special environmental conditions make it a suitable habitat for bats and add to the geological appeal of the area. The cave has two separate chambers, one in the upper part and one in the lower part, and from a geomorphological point of view it is one of the notable features of the region. The access route to the waterfall and the cave starts from the village and continues along two different paths. One is a dirt track passable by SUVs. The other is a pristine, adventurous route through the valley, with steep slopes and a risk of rockfall.

To reach Aghsu Waterfall, you need about 15 minutes of easy forest walking along the river, during which you have to wade across the water several times. Thanks to its untouched nature and scenery, this trail is one of the most attractive parts of the visit. The best time to visit is spring and early summer, when the landscape is at its greenest and the water flow is at its peak. Practising responsible nature tourism is essential to preserve this pristine ecosystem. Keep the trail clean, avoid damaging the vegetation and stay out of dangerous routes.
