Wadi Hanifa, Wadi in Riyadh Province, Saudi Arabia

Wadi Hanifa is a valley in Riyadh Province, Saudi Arabia, that runs from the northwest to the southeast, cutting through the city of Riyadh. The valley floor is wide and shallow, with a concrete bridge spanning it, and the surrounding land is rocky with scattered stone blocks and a sandy path.

The valley was known as al-Irdh in ancient times and was later named after the Banu Hanifa tribe. It has been a site of settlement and agriculture for centuries, with Diriyah and Riyadh built on its banks.

The valley is a popular spot for families and groups who come to walk, cycle, and enjoy the open space. On weekends, you will see people picnicking on the grassy banks and children playing near the water.

The valley is easy to reach from Riyadh by car, with several entry points along its length. Visitors can park near the main recreational areas and walk along the paved paths that follow the water channel.

The valley is home to a bio-treatment plant that uses weirs to naturally clean the water, supporting both wildlife and recreation. This system helps maintain the valley as a green space in the middle of the desert.
