This is where the training for your water, grass, and ice type Pokémon gets really good as you will meet Riley who has a level 34 Lucario. He will fight with you turning all wild Pokémon encounters into multi battles. Also it is suggested to face all the trainers here two at a time so Riley can battle with you. Riley will heal your Pokémon after each battle you have that Riley is involved with.

Head straight and you will battle with Hikers Damon and Maurice. Go past them and just north of the stairs is an Ultra Ball. Go south and at the fork go to the right until you see a barrel. On the barrel is a hidden Full Restore. Turn around and go down the leftmost path and you will find Workers Brendan and Quentin. Go up the stairs next to the Workers and then go down the next stairs and you will find a Max Potion. Head back towards the Workers. Go south of the stairs and go through the next set of stairs. On the middle barrel is a hidden Revive and to the south is a HP Up. Go back towards the Workers again and go right past the barrel that had the hidden Full Restore. Continue following the path east and you will find Black Belt Kendal and Battle Girl Tyler. Continue south and go up the stairs to the right and go north to find a Magnet. Head south and go past the stairs to a pit. In the pit is a hidden Iron Plate. Go back to the stairs and head west and up the next stairs to fight Ace Trainers Jonah and Brenda. Go down the stairs and follow the path to find the Galactic Grunts.

Riley says that the grunts are the reason for agitating the Pokémon here and he doesn't want them to bring any trouble into his mine. The grunts then say they are stealing all the Pokémon here and no one can stop them. Riley then asks you to take them down with him.

After defeating the grunts, Riley will hand you a Pokémon egg as a thanks for helping him then you two part ways. To get out go down the lift and go through the cave to the left and you will be in the final room.
