ION Observation Deck offers a great view of the city and nearby islands. To enter this observation deck, you have to shop here and spend S$20 for a ticket. The ion app does not support sharing tickets between families. If you spend more, they will give you five tickets. If you want to see the view, you can try it here. However, there is another free top-floor viewing area in Singapore. It is not the tallest building in Singapore, but it is about 24th high. It has 55 floors and can take the elevator to the top floor, and the Sky Observatory is located on the top floor. There is also a Salt Grill and bar on the top floor. However, it is the tallest building around Orchard Road and the view is spectacular if you like high views. There is a charge to get in and start your journey from the 4th floor of the ION Shopping Centre. If you like high views, the view is great.
