From MBS sky park

The MBS complex is topped by a 340m-long SkyPark with a capacity of 3,900 people and a 150m infinity swimming pool, set on top of the world's largest public cantilevered platform, which overhangs the north tower by 67m.

For the ticket fare of 20 sg dollar, the park itshelf I would say is not really worth the price, partly due to inaccessible to the side with the swimming pool.

Still, the panoraomic view is stunning, breathtaking, but since the side with the swimming pool is blocked, a 360° view of the scenery around is not possible, thus the 20 sg dollar fare is still rather stiff.
