At The Top, Burj Khalifa - Levels 124 and 125
Enter through Dubai Mall on the lower ground floor and ride one of the world's fastest lifts to the observation deck on Level 124. Step out onto the open-air terrace for 360-degree views over the Gulf, the desert and the city laid out below, then move up to Level 125 for the interactive telescopes and quieter viewing space. After dark the Dubai Fountain performs directly beneath you. Allow about ninety minutes including entry.
