Officially known as Road 59, the road passes through the Alborz Mountains and offers travelers beautiful views of mountains, rivers, forests, valleys, waterfalls, and mountain villages along the way.
Chalus Road is not merely a route connecting Tehran and northern Iran; it is also a popular tourist destination in its own right.

The road is approximately 160 kilometers long, with sections located in both Alborz and Mazandaran provinces.

History of Chalus Road
The present-day Chalus Road was constructed during the Pahlavi era. Before the road was built, transportation between Karaj and the northern parts of the Alborz Mountains mainly took place along mountainous and unpaved routes, making easy vehicle travel between Karaj and Chalus impossible.
Construction of Chalus Road began in May 1931 and was completed in less than three years. The road officially opened on December 3, 1933. Considering the mountainous terrain of the Alborz Mountains and the limited availability of modern road-construction machinery at the time, building such a route was a major and challenging engineering project.
The opening of the road made travel between Tehran, Karaj, and northern Iran much easier. Gradually, restaurants, accommodation facilities, and tourism services began to develop along the route.
Kandovan Tunnel: An Important Part of Chalus Road History
One of the most important engineering projects along this route was Kandovan Tunnel.
After Chalus Road opened, crossing the Kandovan heights in winter was difficult. Heavy snowfall and freezing temperatures could sometimes make the route impassable for long periods. For this reason, construction of Kandovan Tunnel began in 1935, and the tunnel was opened on May 17, 1938.
By passing through the mountain, Kandovan Tunnel shortened the difficult route around the mountain by approximately 13 kilometers, making travel through this section easier. Today, in addition to its transportation importance, the tunnel is considered one of the historic symbols of Chalus Road.
What Is the Chalus Road Route Like?
If you start your journey from Karaj, the road gradually leaves the urban environment and enters the mountainous region of the Alborz Mountains.
At the beginning of the route, the Karaj River and Amir Kabir Dam are among the main attractions surrounding the road. The route then continues toward Asara, Adran, Gachsar, and Kandovan.
As you approach the higher elevations, the landscape becomes increasingly mountainous. Along different sections of the road, travelers can see deep valleys, rivers, rocky cliffs, waterfalls, and mountain villages.
After passing through Kandovan Tunnel, the road continues toward Siah Bisheh and Valiabad, eventually reaching Chalus.
