32 Once-in-a-Lifetime Experiences to Add to Your Bucket List

4. Ride the World’s Longest Zipline Over the Arabian Desert

If you’ve ever dreamed of flying like a bird, this once-in-a-lifetime adventure is for you. The Jebel Jais Flight in the United Arab Emirates holds the record as the longest zipline in the world, stretching an astonishing 2.8 kilometers (1.7 miles) over the rugged peaks and deep canyons of the Jebel Jais mountain range. From the moment you take off, you’ll be soaring through the desert sky at speeds of up to 160 km/h (100 mph), with nothing but stunning mountain vistas below you. Suspended 1,680 meters (5,500 feet) above sea level, this exhilarating ride feels like flying, as the strong desert winds rush past you, and the vast, open landscape stretches to the horizon. For an extra thrill, you’ll be harnessed in a "superman" position, lying belly-down as you glide headfirst across the sky, making it one of the closest experiences to human flight you can get. The moment you reach the landing platform—suspended high above a cliff—you’ll be left breathless, adrenaline-fueled, and eager to do it all over again. Best Time to Go: October to April, when the weather is cooler and more comfortable for outdoor activities.
