If you spend in the mall, you can enter the observation deck for free, and you can quickly arrive by elevator. The opening hours of the attractions are not fixed. First of all, you will see a short introduction to Singapore, surrounded by large glass floors. The telescope is provided, you can enjoy the scenery 360°, which is very suitable for taking pictures. There is a restaurant and bar on the top floor, which are connected to the viewing gallery. Those who want to enjoy the night view can dine there.
Ion Sky provides an amazing and free space for enjoying the cityscape of Singapore. Located at the 56th level of Ion Orchard Shopping Mall, the space is also provides the knowledge about clouds to its visitor. There's also a resturant with the great view of Singpore's sky. One of my most favorite place on Orchard Road.
Why go to ION Sky? Because it's freeeee! (In an expensive city) + awesome views of Singapore. Just make sure to check the operating hours.
Quiet airconditioned space with seating, you will be rewarded with panoramic views of Singapore from ION Sky on the 55th floor of the ION shopping mall. It is accessible via an art gallery on the 4th floor. Ask the concierge, preferably the one situated just outside the mall-side MRT exit gates, for directions. Open between 3pm - 6pm with last entry at 5.30pm. There is a restaurant at the top as well but many go up for a quiet rest.
