The world's tallest manmade structure, the Burj Khalifa is 2,722 feet tall. And while you may think it's pretty awesome, there are some, who have created an even more awesome experience, in the form of BASE jumping. The stupefying stunt was carried out – illegally of course, by David McDonnell and Herve Le Gallou in 2011 when they jumped from the 160th floor. But for those of you wanting a more docile experience of the giant tower, there's a lookout platform on the 148th floor. Easy to access from well-located residences in Dubai, this is one attraction worth visiting.
