The Battle Park (バトルパークBattle Park) is a facility located in the Fight Area which serves as a checkpoint to entering the Battle Tower. It is also home to the Point Exchange Corner, where Trainers can exchange Battle Points received from their successful fights to acquire rare items.
The Battle Park is reached through a series of stops where the Trainer will receive the Point Card in order to catalog the number of Battle Points attained. After this the Trainer will progress through a garden with several Trainers to underneath an arched building called the Point Exchange Building. After going past the Point Exchange Building, the Trainer will come across the Battle Tower.
The Battle Tower is the only Battle facility in Pokémon Diamond and Pearl versions, and features many different modes of Pokémon battling. Such are as follows:
Single Battle: Take three Pokémon into battle from your party and face off against a continuous line of opponents in sets of seven battles. In the 21st and 49th battles respectively, the Trainer will face off against the Frontier Brain, Tower Tycoon Palmer.
Double Battle: Take four Pokémon and battle a series of opponents in a two-versus-two battle. When the Trainer reaches the 21st and 49th battle, he/she will face off against the Frontier Brain.
Multi Battle: Select two Pokémon and enter a battle alongside a friend, in which the first Pokémon from both parties will take the front line against two other Trainers' Pokémon.
Wi-Fi Battle: Choose three Pokémon and connect to Nintendo Wi-Fi Connection, whereupon the player can face off against another player from across the world in Single Player mode.
When the Trainer wins a successive round in the Battle Tower, he/she is rewarded with a certain amount of Battle Points, which in turn can be used to purchase specific items. A list of such items are as follows:
