Tochal Telecabin (gondola lift)
Tochal Telecabin  is one of the world's longest gondola lift lines with a length of 7500 m. The project started in 1974 and has been open to the public since 1978. It starts at the Velenjak valley in the north of Tehran at an altitude of 1900 m. and ends at the last station at an altitude of 3740 m., near the main ridge of Mount Tochal. This gondola lift is used for accessing ski resorts and other recreational centres on the mountain. Beautiful landscape, mountain fresh air and a multitude of fresh water springs adds to the freshness of the area.
