The first thing that springs to the minds of any Iranian after hearing the name of Ahvaz is Karoun river. Karoun is the largest river with 850 KM long and is the only river in Iran that runs to international waters and then to the ocean. This river passes through the middle of the city and divides Ahvaz into two parts of east and west. There are currently 8 bridges installed for the cars as well as two other bridges for the pedestrians. Karoun river Is a place where one of the first civilizations was created next to it and the sign of life and prosperity have always existed on the banks of the river. Karoun is the only navigable river in Iran due to its width and high water flow rate. During the Qajar period, shipping was done on this river and Iranian and British merchants could import and export their goods via the Persian Gulf. The beauty of Karoun is not ignorable and the stunning riverbank, in addition to being home to many migratory birds, welcome visitors with a variety of tastes who come to the coastal road for recreation activities.
