Apparently, there are two possible answers to the question of how to get to the eighth gym on Pokemon platinum. The regular way is to first of all beat Giritina.
There should be a stairway on the right, leading up to some sort of glass structure. This stairway, previously blocked by a man, should now be clear. Sunyshore Gym, the eighth gym, should be at the top.
This is followed by taking the stairs on the right, pressing the red button on the right once and again taking the stairs on the right. We have no confirmation, however, whether this actually works.
