Jebel Jais (Arabic:جبل جيس,romanized: Jabal Jays) is a mountain of theNorth-Western Hajar range in theMusandam Governorate ofOman and also inRas Al Khaimah,United Arab Emirates. The summit has an elevation of 1,934 m (6,345 ft).[1] 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 1,892 m (6,207 ft) above sea level, and with around 10m ofprominence.[citation needed] Since the summit is on the Omani side,Jabal ar Raḩraḩ, at 1,892 m (6,207 ft), is the highest peak in the UAE, with significant prominence.[2]
On the Omani side, the mountain is largely underdeveloped, inaccessible, and far from any development, however, on the United Arab Emirates side there has been a lot of development in recent years. A 36 km (22 miles) road has been built, whichhairpins most of the way up the mountain on the United Arab Emirates side.[3] 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 longestzip-line and anEtisalatcell 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.[4] A private brick road then continues further up, toSheikhSaud Bin Saqr Al Qasimi's palace, which is situated near the UAE's highest point. Thesummit is then accessible by hiking, a short distance after the palace perimeter fence. The mountain is 100 kilometers in width and 700 kilometers in length. It is the highest mountain range in the region.[5]
The road was completed by September 2019.[6]
The mountain, and the highway to its peak, feature prominently in theUAE Tour, an annualroad cyclingstage race, first held in 2019 as part of theUCI World Tour. Due to the difficulty of the long, steep climb, the stage that finishes here is usually considered thequeen stage of the entire UAE Tour. Previous winners of the Jebel Jais stage includeGrand Tour and UAE Tour winnersPrimož Roglič andTadej Pogačar.[7][8]
The world's longest zip-line opened on the mountain in February 2018. It is 2,832 m (9,291 ft) long, and users travel at speeds of up to 150 km/h (93 mph),[9][10] 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. The cost is around $98 to $122 or €89 to €111.[11]
The temperature of Ras Al Khaimah tends to be lower than in other parts of the country. Temperatures as low as -5 °C[12] have been measured at the top of the mountain in winter. Sometimes humidity level is likely to increase during night and early morning over some coastal and internal areas.[13] The temperatures at the highest elevations on the mountain tend to be lower than other parts of the United Arab Emirates, by about ten degrees, except for spots such as the mountains ofHafeet,[14] Yibir,Yanas andAl-Heben.[15]
