Adaran Waterfall

Adaran Waterfall is located in the Adaran area, near the village of Orangeh (Arangeh) in Asara District, Karaj County, Alborz Province. It is one of the most notable natural waterfalls along the Karaj–Chalus road. The waterfall lies in the heights of the northern Alborz range and is also known in local sources and among residents as "Pich-e Adaran Waterfall". Its height is reported to be about 90 metres, and together with the smaller waterfalls and springs around it, it creates a spectacular view in the heart of green valleys.

Adaran Waterfall is an important part of the nature-tourism experience in Arangeh. Thanks to its great height and its seasonal flow, it is one of the favourite destinations for travellers in the wetter seasons of the year. The access route usually runs alongside the Arangeh River, between rocks and through willow trees and other rare northern plants, creating a beautiful natural setting. Parts of the route may require crossing water, and some rocky sections call for care, so good physical fitness and suitable footwear are essential.

To reach Adaran Waterfall, first take the Tehran–Karaj freeway and then follow the Chalus road north to the exit for the Arangeh area. Once you reach the Adaran area, local footpaths and natural landmarks guide you to the waterfall. The best time to visit is usually late spring to early summer, when there is more water and the weather is milder; in dry seasons the flow may decrease. Following the principles of responsible nature tourism, such as taking your rubbish back with you, not lighting fires and not damaging the vegetation, is important for preserving the beauty and ecosystem of the area.
