10. Dubai, United Arab Emirates
Dubai is home to a bevy of superlatives, including the tallest building in the world (Burj Khalifa at 2,717 feet), the world’s largest indoor theme park (IMG Worlds of Adventure), the largest man-made marina in the world and the world’s first rotating skyscraper, set to open in 2020.
If those aren’t enough reasons to visit, the city is also home to an indoor ski center, one of the globe’s largest shopping malls and multiple public beaches – not to mention a handful of man-made islands. A trip here won’t be cheap, but it’s worth it.
