Dosar Cave

Dosar Cave is located near Mehriz in Yazd Province. The cave was discovered in the winter of 1391 (2012–2013). It contains the largest underground chamber in Iran and the fourth-largest cave chamber in the world. According to survey mapping, the chamber covers an area of about 81,500 metres. This oval-shaped chamber is 385 metres long, 265 metres wide and 70 metres high. Dosar Cave is in the Kalmand area of Mehriz, about 85 kilometres from the city of Yazd. After turning onto the Mehriz road, travellers drive about 60 kilometres to a dirt side road, which lies opposite the dirt track leading to the Chah-e Morti farm.

Dosar Cave, sometimes mistakenly known as Poshum, not only holds the title of the largest underground chamber in Iran but is also listed internationally, ranking fourth in the world for cave chamber size after Malaysia, China and Spain. It should be said, however, that this remarkable cave is still not well explored; yet it has the potential to become, in the near future, one of the country's research hubs for specialists' study and investigation.

On the walk to Dosar Cave, visitors pass a water reservoir (ab-anbar) and a place used to keep flocks of sheep. After entering the cave, the first striking feature is a 19-metre-deep pit, which is reached by a series of steps and a slope of about 70 degrees. Before long, the route turns into a watercourse, and another pit, 80 metres deep, appears in front of visitors. At the bottom of this pit lies a vast, spacious chamber that creates a plain-like space. The cave is at an altitude of 1,900 metres above sea level, with an area of 81,500 metres and a depth of 130 metres. On the cave floor you can also see large and small rocks, which show where the chamber's ceiling has collapsed and add to the beauty and mystery of this wondrous space.
