Gavkhuni wetland is one of the most well-known wetlands in Iran and is one of 19 international wetlands and has a worldwide reputation.
The wetland or swamp of Gavkhuni is located next to the historic Varzaneh city and near the entrance of the beautiful Varzaneh Desert. Before you reach the wetland until the eye is working, you see a desert and dry plain. This wetland lies at the end of the Zayanderud and originates from it. The river, which originates from the Zard-Kuh mountains of the Bakhtiari, pours into this wetland after crossing Isfahan city. Due to the dryness of the Zayanderud, the wetland also dried up. But this year, due to heavy rainfall, the Zayanderud was filled with water and revived the Gavkhuni wetland. The deepest part of the wetland reaches 150 centimeters. The wetland covers an area of 470 square kilometers, but only 50 square kilometers is water. On the southern margin of the wetland, there is a vast amount of salt, due to the high evaporation of water and the accumulation of salt crystals created. The salt of this sector is extracted and used.
