There are a total of 327 steps taking you to the first platform, where you can stop and admire the views, and then there are a further 347 steps to take you to the second floor.
There are also interspersed landings where you can stop and catch your breath (and the views) as you ascend. It takes roughly 30 minutes to climb the stairs from the ground floor to the second floor, with breaks to admire the views in between.
There is plenty of space to walk around, and it’s where you’ll find the cafes and seating areas. And there were official photographers on the first-floor grabbing people for photos.
As the tower rises the width decreases. So the room on the second floor will be less than the first, but more than the third! There are more open air sections on the second floor for those expansive views and photos.
I’ve heard many others say the view from the third floor is really no different to the second floor, it’s just higher up, but there are also higher barriers, less space, and more haze!
