Im Prolly sounding sooo dumb but Team Aqua say that "we have to find Magmas..

Once you have visited mt prye and gotten the magma seal go to the Mt Chimney steps right by Flannery's town where the team rocket person was it will open and you will find team rockets hide out.

Team Magma's hideout is beneath the Jagged Pass. If you have the Magma Emblem, a boulder will 'shake in response' to the Magma Emblem. You have found the Team Magma Hideout.

The hideout is where you find team magma on the moutain with the lava flow (where you get the medeorite in the funky machine). Go down that hill with the "Magma Emblem" with you and you will find it.

To get to team magmas hideot first you have to ride the cablecar near lavaridge town and when you get to the top go down the cliffs straight down the midddle untill you see either a hole in the wall or a team magma member if it's a hole just go in if it's a team magma member you forgot to do something first.

It's at the jagged pass where you fought them before.

You have to have the magma pendent to get in.

You get that from Mt. Pyre. Hope this helps.

The Magma Hideout is on Jagged Pass. You must have the Magma Emblem to access it.

You have to get the team magma emblem from the old man and woman at the top of mount Pyre ( where the orbs where stolen from) and then go tothe top of mount chimney (next to Lavaridge town) and go down the path to lavaridge town with the emblem and the door will show itself when you get there.

Well, first you have to kick Team Aqua's butts at Mt Pyre, then the old woman will tell you Team Magma were there first and she will give you a Team Magma Emblem. Go to Jagged Pass. Find a big rock. The game will pause and the screen will start to shake. There will be an opening in the rock so you can go in and fight Team Magma! Bring some good Pokemon!
