Pokemon Brilliant DiamondandPokemon Shining Pearltake and expand upon one ofPokemon Diamond/Pearl/Platinum’s iconic features: The Underground. Originally, players would go into the Underground to mine treasures or set up their secret base. InBrilliant DiamondandShining Pearl, players can catch Pokemon in what is now called the Grand Underground.
The Grand Underground appears totake heavy inspiration from the Wild AreainPokemon SwordandPokemon Shield. Instead of finding Pokemon in random encounters, players can see Pokemon walk around. However, going into the Grand Underground for the first time will reveal that certain areas are unavailable. To unlock all of the Grand Underground, players will have to progress inBrilliant DiamondandShining Pearl’s main story.

Grand Underground Zones

If players use the Y button in the Grand Underground,they can either Go Up/Leave, Call, or open up the Grand Underground Map.
Pull up the map, and it will become evident that areas of the Grand Underground are sectioned off from one another.The Grand Underground is divided into zonesthat become available as the player advances through the story.
Use the Explorer Kit in the following locations to unlock all regions:

In the beginning, players will have access to the Western Zone. Once they end upon the other side of Hearthome City, using the Explorer Kit will take them to the Eastern Zone instead.
Pokemon Hideaways
