Once a waste disposal site, Wadi Hanifa is now a beautiful valley running a length of nearly 120 km from the northwest to the southeast of the capital.
Known in the pre-Islamic era as Wadi Al-Irdh, it was renamed Wadi Hanifa after the Bani Hanifa tribe that populated the area.
Riyadh grew substantially and expansion destroyed the environmental balance in the scenic valley, leading to erosion.
“The once fertile and scenic Wadi Hanifa suffered as the capital city rapidly expanded,” said a local, adding that the growing city used the river valley as a throughway for utility lines and a dumping ground for construction waste. Later, industrial activities were launched in the area, turning it into a dump for waste disposal.
In 1986, the Arriyadh Development Authority (ADA) launched a plan to turn the dump into a nature reserve, attracting local and foreign visitors, and encouraging investments. The redevelopment plan involved creating water channels, trails, and spots for visitors to observe the spectacular views the valley has to offer.
Riyadh’s first large sewage treatment facility channeled 400,000 to 650,000 cubic meters of runoff daily, creating an area of small lakes south of Riyadh. This area grew and a 100 km green corridor was created.
According to the ADA, the decision taken in 1986 proved to be a significant milestone as it helped transform the valley into the largest natural reserve in the Kingdom. The wetlands became a stop for migratory birds and a popular area for recreation.
The valley, located on the outskirts of the capital, has water channels, green corridors, walkways and picnic spots for visitors to enjoy the scenic beauty that includes orchards and farms, making it a major attraction for both Riyadh residents and visitors.
Abdullah Ahmad, who resides in the nearby Wadi Laban area, said: “Riyadh residents were in need of such a site in the city, having the opportunity to enjoy nature and a clean environment away from built-up places.”
Zakir Khan, a regular visitor to the natur reserve, said: “It’s a great place for a picnic. I go there all the time with my family for a barbecue… Surrounded by mountains and a lake, it is a beautiful and quite popular place among picnickers. The best part is, it is not even far from the city.”
