You will be looking for different Pokémon as you explore the Sinnoh region. There are Pokémon all over the place and you will need to know where to look to find them all. When it comes to finding Pinsir, you will need to look for it in a specific location. In this guide, we will share with you where you can discover Pinsir in Pokémon Brilliant Diamond and Brilliant Pearl.
It is important to note that Pinsir is a Shining Pearl-exclusive Pokémon. You will only be able to find it if you have this version. If you have a Brilliant Diamond version of the game, you can't find it. The only way to receive Pinsir is to exchange it with another player who owns Pokémon Shining Pearl.
For those with Shining Pearl, you will be able to find Pinsir when you are in the Grand Underground. You will be able to search for this location when you receive the explorer kit from the old man in Eterna City. While there, Pinsir usually spawns in the Big Bluff Cavern, Still Water Cavern, any cave with grass, or any cave with water. You shouldn't have too much trouble tracking it down and adding it to your Pokémon collection.
