The 86th Floor
After visiting the Skybridge on the 41st floor, you're taken up to the 86th floor (fyi, the Petronas Twin Towers have 88 floors).
This is a view from one of the many windows. This side shows the other tower and the city of Kuala Lumpur.
Apart from being able to walk around and take photos of different views of the city, there are miniature models on display and information kiosks to play around with.
You're given around 20 mins to explore before being taken back down to the ground floor, ending your tour at the gift shop.
