You can get there by Diving in the large area of dark water on route 128 and then by going into the underwater cave and then surfacing there. You will be in the Seafloor Cavern of Team Magma. When you find your way to Maxie, he battles you and you will see Groudon. Groudon goes off somewhere and you see Archie and you all go outside with the flashing light. When Maxie and Archie go, you Fly to Sootopolis and Maxie and Archie will be by the Gym. You Surf to the left and go up the stairs to the top of the town and then over to the right and Wallace the Gym Leader with Steven will be there. They talk to you and you go into the Cave of Origin Where you find Groudon(it's easy to find him). When you catch him(don't use your Master Ball, save it for Latios, or make him faint(not recommended), you come out and you can battle Wallace.
