It's the little square area next to Snowpoint City and you need to beat the Elite Four to get there

It's in the battle frontier at the battle area
After you beat the Pokemon league and get the National Dex, you will be able to get to the Battle Zone. The battle zone is comprised of 3 areas: the fight area included. The fight area is basically a place to test your skills as a trainer as you strive for the top of the battle tower.
beat 50 trainers
you have to beat all 7 trainers in all 5 buildings
Like Diamond and Pearl you go on the ship at Snowpoint City and sail to the Battle Zone. To get to the Survival Area and the Resort Area you must get your National Pokedex.
