At the top of Orchard Road's most fashionable shopping mall and luxury condominium complex is ION Sky, the 55th-level observatory that's open to the public. Buy tickets from the concierge counter on level 4 of the ION Orchard Shopping Mall, and enter the express lift inside the ION Art Gallery. The panoramic view of Singapore is aided by the use of a Behold telescope similar to that found in Dubai's Burj Khalifa, the world's tallest tower. The Behold is a high-definition camera that projects images onto a screen for easier viewing. Viewing is permitted in 2-hour slots, at 10am, 2pm, 4pm, and 6pm.
