Burj Khalifa

The Burj Khalifa is a stunning feat of architecture and engineering, with two observation decks on the 124th and 148th floors and a restaurant-bar on the 122nd. The worlds tallest building pierces the sky at 828m and opened in January 2010, six years after excavations began. To avoid wait times or expensive fast-track admission, book tickets online as far as 30 days in advance. Note that high humidity often cloaks Dubai in a dense haze, making views less than breathtaking.
