Galar Mine No. 2 is located on the far east side of the Galar region map, between Hulbury to the north and Motostoke Outskirts to the south.
Unlike Galar Mine, Galar Mine No. 2 offers Trainers a chance to cast their line into the water—there are six fishing spots—in hopes of catching Chewtle, Corphish, or Barboach. Other wild Pokémon include Gastrodon (East Sea), Shellos (East Sea), Shuckle, and a few others.
In addition, a trio of Trainers are waiting to battle you. And if you have the Water Mode Rotom Bike, you can easily retrieve TM53 Mud Shot.
