The Team Galacyic base the the Galactic building in Velstone. Just go left of the pokemon center and go up the stairs.
What you do is after you've visited Lake Aqurity, you need to go to Galactic HQ and talk to the grunt.He will say something and leave the key to the basement. The next thing you need to do is that you need to go on many stairs before you get the Galactic Key.trade with another ds
Yes there is the underwater base was the Aquabase which was the base for the Lightspeed team in Power Rangers Lightspeed Rescue.
When Team Magma are discovered and use the blue orb on Groudon there is a passage; a man is in there and he will give you the Master Ball. Don't use it on Groudon; use it on Rayquaza - you'll probably think you're not going to catch Groudon with an Ultra Ball, but you'll know when you are fighting Rayquaza that he's hard. If you miss the Master Ball, you can't go back for it. Team Magma have to be there.
Did you release them from Team Galactic's HQ(?)? If not go there (you'll fight a bunch of Galactics first) and then you'll see all three of them captured. Then you'll have to push a button. They'll go off into their caves. If you already released them then they should be in their caves already. Unless, you ran away from them or killed them. If you did one of those to them, you won't be able to see them again.
I'm not sure because I did that a while ago but I think you need go to the lake of rage and battle the red gyarados. After you have defeated or caught it go back to the shop and Lance will open the doors. I'm not sure if this is the exact answer your looking for but this might be helpful.
You go to team galactics base and pick up the key outside and adventure through their other base
