Ghar Parau is a cave in the Zagros Mountains, north of Kermanshah in Western Iran. It is the deepest cave in Iran.This cave was registered as a National Natural Monument by Mr.
Farshad Fattahi in Department of Environment of Iran.
A British led caving expedition to the Zagros Mountains in 1971 led to the discovery of the cave. The cave was rapidly explored to a depth of -750m and was left with open passage.
At the time the deepest cave in the world was the Reseau de la Pierre St-Martin with a depth of 1,174 m (3,852 ft), meaning that Ghar Parau was an excellent prospect for the deepest cave in the world.[4] The team returned the following year and passed their previous limit, but to their great disappointment the cave sumped almost immediately.
To be "Ghar Paraued" became a term used in British caving for a small, disappointing breakthrough following great effort to discover new passage.
