Tangeh Savashi (Persian: تنگ ساواشی) or Tangeh Vashi (Persian: تنگ واشی) is a gorge and mountain pass in the Alborz range of Iran (Persia). It is a popular tourist attraction in Tehran Province.
Located 15 kilometers west of Firouzkouh, 9 kilometers north of the Firouzkouh-Damavand road in Tehran Province, it is a narrow mountain pass in the Alborz range. The narrow gorge was created by a perennial stream which comes down from a series of waterfalls upstream.
Slightly lower, in a hilly area, the stream provided a patch of lush grazing land within the mountains. Until the 20th century the area was a royal hunting reserve, populated by various wildlife. The Qajar Persia king Fath Ali Shah (1772 – 1834) maintained a hunting lodge there.
To commemorate his hunts, Fath Ali Shah ordered the carving of a relief in the mid way point of the pass. There are ruins of a Qajar guard tower at the top of one of entrances to the gorge.
Today, the relief is a popular tourist attraction and the location is also highly popular among trekking and hiking fans.
