Here's how to get there. You go to the safari zone to the part where you find even more Pokemon. You will find a path where you can walk on trees. It will bring you to a little clearing. There will be an item. Pick it up. It is the gun. Go to key items and click use on gun. You will start floating up. Once you get to hell, talk to the devil. He'll put you on the hidden islands. If you use the gun after that, you can go battle the devil. He has a Mewtwo Lv. 95, and a Charizard Lv. 94.
The "secret" islands, Southern Island, Faraway Island, Navel Rock, and Birth Island, are only accessible by obtaining a ticket from a Nintendo Event that goes to the certain island.
