Kul Khadang Strait is a beautiful way to climb the peak of Kolunchin (Zardkooh). At the beginning of this route, you will see the lofty and amazing walls of the mountain with yellow and brown views and huge monolithic rocks, and in the continuation of the valley, you will move near the plants and greens to finally reach the long glaciers. This glaciers cover the whole valley and you have to walk for miles over them. In the beginning of this valley, you will come across one or two small springs of clear water. Other than that, we will not reach another spring on the rest of the way, and we will only have access to the water flowing from the melting snow.
The high walls with monolithic rock cliffs with amazing shapes and with yellow, brown, black and gray colors are the prominent and glorious features of Kul Khadang Strait. Perhaps the name of this mountain (Zardkooh that means “Yellow Mountain”), is due to the various yellow and brown colors of the mountain walls.
