Cheekha Dar lies on the Iraq - Iran border in the Zagros mountain range of Kurdistan. It is the highest mountain in Iraq, but there are higher mountains in the range. The CIA and Russian topographical mapping claims it is 3,611m. It was climbed in November 2004 by English explorer Ginge Fullen, and the first reported winter ascent was by Jonathan Beswick and Matthew DuPuy on March 18th, 2011. Last successful attempt belongs to explorer Peter Gregor and mountaineer Martin Juris from Slovakia in 2018. Cheekha Dar is Kurdish for "Black Tent".
The mountain base is accessed from Erbil, a major town in Kurdistan, you can fly to Erbil from various places, or drive overland from Turkey. From Erbil travel North East on Route 3 to a village called Gundah Zhur. From Gundah Zhur it is a days walk up to an old Kurdish Kut on the mountain. This route goes through a minefield and so it is essential to get Kurdish Army guides. This hut can be used as a Basecamp for a summit attempt, which can be done in a day but is better broken down to two.
This is an area that see's no visitors, so be aware, because you are moving in very sensitive area very close to border with Iran (even on the top lateau is military base of Iranian forces, they usually leaving the place when the winter comes). It is very dangerous to climb the mountain without any guide - presence of Kurdish fighters and smugglers.
You can ask for shelter in local Kurdish villages, stay at the Kurdish hut or camp anywhere on the mountain.
