Chalus Road (officially called Road 59) is a very beautiful asphalted road located in Chalus, a suburb of Tehran, the Iranian capital. The road becomes dangerous because due the narrowness and the mountainous terrain.
The road is difficult and it’s a nightmare in the wet or dark (or both). The surface of the road is asphalt, and chains or snow tyres can be required anytime. Approaching from Karaj to the south, the road initially leads through jagged cliffs, then on the north side of the range through endless old-growth beech forests that wolves, lynxes and bears all call home. Then, at last, the Caspian Sea appears on the horizon.
This road, which displays a variety of sceneries from green to snow clad surroundings to rocky mountains in the north, is usually open all year, but during winter months, it can be closed when the access is not cleared of snow. In winter, avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous due to frequent patches of ice.
The road is in dreadful condition and requires strong nerves to negotiate it. Any barriers along the edge afford little more than token protection; large stretches should be taken at a snail's pace and a lookout kept for vehicles coming from the opposite direction! The road's winding design, providing stunning panoramic views, is very curvy and fun for a leisurely ride, so it pays to take it slow. Exercise extreme caution when passing on-coming traffic, over-taking and around corners.
