Where Is The Fight Area In Pokemon Platinum?

Same as Diamond and Pearl. After you defeat the Elite Four and the Champion, fly to Snow Point City. Walk south till you see some water. Head west a few steps and you'll see a sailor on a dock with a ship (that has drills) behind him. Ask him to take you to the Fight Area.

You have to beat the elite four then go to snow point city and travel in the ship.

After you beat elite 4 go to snowpoint and go in the boat where the man is standing

After you beat the elite four and the Champion fly to snow point city ask the man with the bout drill and he will take you there

You go to snowpoint city after defeating the elite fourgo to sailor and say yes.
