The Wadi Danhah flows from north to south, west of and almost parallel to the
mountain range of
Jabal Wamm (), and has a total length of approximately ''''''. Its main
river source is located at an altitude of approximately , on the southern slope of
Jabal Ayuzah (), within the United Arab Emirates, a short distance from the border with
Oman. In its upper reaches, the wadi descends with a moderate gradient. Its bed, however, is full of loose rocks, sudden drops, and some dry waterfalls, making it difficult to traverse and only accessible with
rock climbing techniques. In its middle course, Wadi Danhah forms a deep
gorge where erosion caused by the water flow has exposed the multicolored layers of
stratified sedimentary rocks, highly polished and of high hardness, predominantly in reddish, ochre and white tones. Although the area is not easily accessible, this picturesque landscape attracts numerous visitors and has become a popular tourist and hiking destination. For advertising and marketing purposes, some companies promoting guided tours and outdoor tourism activities refer to
Wadi Danhah with the marketing names
Rainbow Valley or
Spectrum Valley, and also by the erroneous name
Wadi Ghub. In its lower reaches, two kilometers before its mouth, Wadi Danhah passes through the village of
Danhah (), with an area featuring small farms, cultivated terraces, and lush palm groves. This area has been severely affected by the operation of large, now abandoned, quarries. In the vicinity of the current town are the ruins of the old village, practically destroyed. Next to its mouth in the
Wadi Al Fay lies the village of Ghub, which has expanded in recent years to the west of the central area of the Dibba / Sayh Dibā
floodplain (). == Dams and Reservoirs ==
