The mountain
Jebel Jais is the highest point in the UAE — 1,934 metres of folded limestone rising sharply out of the Hajar range on the Oman border. The road that snakes up it was finished in 2018 and is now a destination in its own right: 36 km of hairpins through dry wadis, with viewpoints at every switchback.
Two-thirds of the way up, a purpose-built launch pad clings to the cliff at 1,680 m. That's where the zipline starts.
The launch
You're harnessed face-down, Superman-style, into a horizontal frame and clipped to the cable. The platform falls away beneath your feet, the operator counts to three, and the floor opens.
The first 30 seconds are pure acceleration — by the time you cross the ridge below the launch you're already at 100 km/h, with the mountain falling away on both sides and nothing but wind in your helmet. Top speeds during the dive hit 150 km/h.
The full ride lasts a little under three minutes, ending on a platform suspended in mid-air across the valley. From there a second, gentler 1 km zip carries you back to a road-accessible landing.
Make a day of it
Pair the zipline with a meal at 1484 by Puro — the UAE's highest-altitude restaurant, perched on the next ridge — or extend with the Via Ferrata, a cable-protected climbing route across the same cliff face.
If you're driving back to Dubai, leave the summit before sunset; the descent road has no lighting and the temperature swings fast once the sun is gone.
