In 2018 is open to the public from Juli 10 to August 5 entrance was 195Skr (approx $26-28) and takes about 60-80min. you get to the top 54th floor conference floor, inside there is binocular you can use there is a 15min info about the construction, condos, facilities ect.

There are only a few times every year when they have tours. I cannot find anything for this autumn.Maybe you can contact Skyhigh meetings ( The Conference center)to get an answer.

Bus 5 (very close) or 3 (takes you nearby, to the ICA Maxi which is about 2 blocks away).

Im sorry to inform you that this is not a landmark of that sort that you can explore.
