Kunhar River is also known as Nain Sukh. It is 166 kilometers (103 miles) long river, located in North-West Frontier Province, Pakistan. The river originates from Lulusar lake, nearly 48km from Naran Valley.
Waters of Dudipat and Saiful Muluk lakes feed the river besides glacial waters from Malka Parbat and other high peaks in the valley. Kunhar flows through entire Kaghan Valley through Jalkhad, Naran, Kaghan, Balakot, Garhi Habibullah and joins Jhelum River just outside Muzaffarabad in Azad Jammu and Kashmir.
The Kunhar river trout is considered to be the best fish throughout the sub-continent
