The rugged and raw Hajar Mountains dominate the Ras Al-Khaimah scenery and create a beautiful area to head out into nature on a day trip. The surrounding desert has ever changing rust-coloured sand dunes, while in the mountains the awe-inspiring jagged landscapes are the kind of big-sky country that most visitors don't expect to find in the United Arab Emirates. The Hajar are of tremendous interest to geologists as they have the world's greatest surface exposure of ophiolites (igneous rock from the oceanic crust). The highest point in the mountains (and in the country) is JabalYibir(Yiber Mountain) standing at 1,537 m.
