The limestone escarpment that forms the western skyline of Riyadh, visible on clear days as a long flat-topped ridge above the desert. The Tuwaiq provides the closest accessible hiking to the city — the escarpment face and the plateau above it are rugged and largely undeveloped. Several tracks lead up from the western suburbs of Riyadh to viewpoints along the rim, looking east over the city and west into the broad plain of Wadi Hanifah.
The best access points are via the Diriyah area. Early morning or late afternoon visits are advisable — the heat at midday can be extreme. The limestone outcrops hold fossils of marine creatures from when this whole plateau was the floor of a Cretaceous sea. Take water, sun protection, and a charged phone. No facilities on the escarpment itself.
