Tochal Telecabin is one of the world's longest gondola lift lines, with a length of 7500 m. The project started in 1974 by Bahman Batmanghelidj and associates and has been open to the public since 1978. It starts at the Velenjak Valley, 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. The gondola lift is used to access ski resorts and other recreational centres on the mountain. The upgraded safety standards of the lines allow families and athletes to enjoy the ride and the other facilities.
