Overview A visit to Burj Khalifa's observation deck on the 124th and 125th floors is a must-do for every visitor in Dubai. No need to wait in line - booking in advance allows you to go straight to the elevator to ascend the world's tallest tower at 10 meters per second. Once at the top, enjoy breathtaking views of Dubai's skyline, desert and ocean through the floor-to-ceiling glass walls. Make sure to use the telescopes provided for close-up real time views of the areas below. Venture outside into the open-air terrace and enjoy a more clear perspective of the sweeping views of Dubai. Take a moment to look through the souvenir store at the top, where you can shop for friends and family back home.
