After catching/defeating Palkia (Pearl), Dialga (Diamond), or Giratina (Platinum), you are able to go on ahead to Route 222 (which is nearby the Valor Lakefront), where you previously could not go because a man was blocking the way. After that, you have to go to the Vista Lighthouse in Sunyshore City, and the Gym Leader will be there. Then you can go to the gym.
