Big Bluff Cavern is a large hideway situated to the far east of the Grand Underground. It’s a bigger version of a Rocky Cave, but the rare spawns are based on a Grassland Cave.

How to Reach Big Bluff Cavern

From the beginning, if you’re determined, you can travel all the way east along the central band of the Grand Underground to reach this cavern. The closest entrance to the cavern is via the Pokémon League; besides that, it’s not too faraway from the Veilstone City Entrance.

Item Locations
