Tangeh-ye Vashi (Persian: تنگه واشی) (35.8758°N 52.7269°W)[1] is a gorge and mountain pass in the Alborz range of Iran (Persia). 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 grazing land within the mountains.
