The XLine Dubai could possibly be one of the best ways to view the glamorous Emirate.
But one man - an actor named Lee Kwang Soo - probably couldn't think of anything worse, judging by his reaction in this video.
While in the UAE to film his Running Man TV show, the star was challenged to ride the zipline next to the Burj Khalifa, and memorize some areas in the city while he was at it.
But it seems zooming by the world's tallest building - and over the dancing fountains - was all too much for Lee. Watch the clip where he appears far too flustered to retain any information after his thrilling experience.
At 90 meters off the ground and 558 meters in distance to cover between buildings, we're not surprised he was scared.
See him absolutely freak out over the stunt in the clip.
