Jebel Jais
Jebel Jais () is a mountain of the North-Western Hajar range in the Musandam Governorate of Oman and also in Ras Al Khaimah, United Arab Emirates. The summit has an elevation of . The summit is located on the Omani side, but a high point west of this peak is considered the highest point in the United Arab Emirates, at above sea level, and with around 10m of prominence. Since the summit is on the Omani side, Jebel Al Mebrah (also known as "Jabal Yibir"), at , is the highest peak in the UAE, with significant prominence. Infrastructure. On  the Omani side, the mountain is largely undeveloped, inaccessible, and far from any development, however on the United Arab Emirates side there has been a lot of development in recent years. A road has been built, which hairpins most of the way up the mountain on the United Arab Emirates side. Near the top of the road, there are parking places, food providers, toilets and a viewing platform. After a security checkpoint, the road continues up a few kilometers further to the world's longest zip-line and an Etisalat cell tower, as well as a large flat area used  for outdoor shows and parking. New buildings are also being built along this road section, for use of the zip-line operating company. This section was completed towards the end of 2017; however it remains closed to the public, by motorized vehicles, as of December 2019. A private brick road then continues further up, to Sheikh Saud Bin Saqr Al Qasimi's palace, which is situated near the UAE's highest point. The summit is then accessible by hiking, a short distance after the palace perimeter fence. The road was completed by September 2019. UAE Tour Road Cycling Race. The  mountain, and the highway to its peak, feature prominently in the UAE Tour, an annual road cycling stage race, first held in 2019 as part of the UCI World Tour. Due to the difficulty of the long, steep climb, the stage which finishes here is usually considered the queen stage of the entire UAE Tour. Previous winners of the Jebel Jais stage include Grand Tour and UAE Tour winners Primož Roglič and Tadej Pogačar. Jebel Jais ZipLine. The world's longest zip line opened on the mountain in February 2018. It is long, and users travel at speeds of up  to , There are, or have been, plans in place to build a hotel, cable car, paragliding launch ramp, golf course and ski slope following the opening of the road. Climate. The temperature of Ras Al Khaimah tends to be lower than other parts of the country. Temperatures as low as -5 degrees Celsius have been measured at the top of the mountain in winter. The temperatures at the highest elevations on the mountain tend to be lower than other parts of United Arab Emirates, by about ten degrees, except for spots such as the mountains of Hafeet, Yibir, Yanas and  Al-Heben. Snow fall. In January 2009 there was snow on Jebel Jais. This was only the second time snow had been reported in the history of United Arab Emirates, previously having only been seen in 2004. There was less on this occasion. In February 2017 it snowed again on Jebel Jais and the temperatures fell down-to -5 degrees Celsius.
