Qiddiya, Entertainment district in Riyadh Province, Saudi Arabia.

Qiddiya City is a planned entertainment and sports city under construction along the Tuwaiq Escarpment, about 45 kilometers southwest of Riyadh. Its first opened asset, Six Flags Qiddiya City, features 28 rides across six zones, including the pale steel track of Falcons Flight curving above the ground. Nearby stand white tent-like tensile structures with pointed peaks, and the wider site is planned to hold 60,000 buildings.

Announced in April 2017 as part of Saudi Vision 2030, the project had its foundation stone laid by King Salman on 28 April 2018, and construction began in early 2019. Qiddiya Investment Company, a closed joint-stock company owned by the Public Investment Fund, was established on 10 May 2018 to develop the site. Six Flags Qiddiya City opened on 31 December 2025 as the first operational asset.

The name comes from the Arabic al-qadd, the cut or cleft in a path: the historian Rashid al-Asakir links it to the Aba al-Qadd road, which crossed these slopes to connect Al-Yamama with the Hejaz and still exists. The area also holds Wadi Qiddiya, which once drained into Wadi Namar and then Wadi Hanifa.

Highways run west from Riyadh to the site, with the drive taking around one hour, and a future metro connection is expected to provide additional access. The site covers a large area, so visitors should plan for ample walking time and sun protection for outdoor visits.

The Falcons Flight roller coaster at the Six Flags park is designed to become the longest, tallest, and fastest in the world when completed, mimicking the shape of a falcon's flight. The track runs partly over the plateau's cliff edges, offering open views of the desert valley below.
