The most famous attraction of all, the Burj Khalifa is Dubai's iconic landmark and also, the world's tallest building. When visiting the complex, one must not fail to head over to the 124th floor observation deck. The bird's eye views of the city are simply amazing. Your 360 degree views will consist of the desert on one end and the modern city on the other. Plan a night visit and you will be mesmerized by the city, engulfed in a million twinkling lights. Before heading to the observation deck, you may want to check out the surroundings, home to beautifully manicured gardens and walkways, which meander around the water features. Amongst these is the Dubai Fountain, deemed the world tallest fountain, which performs on the same lines as the one at Bellagio, Las Vegas.
