How do I get past Lillycove city?

Go to the Rocket Hideout, talk to the Grunts blocking the entrance, and go to Slateport City and locate the interview in front of the aquarium. In the middle of Captain Stern's interview, Maxie/Archie will order him via megaphone to surrender the submarine. Go back to the hideout, defeat the Admin there and have Maxie/Archie escape, and exit the hideout.

To get through lilycovecity go to the leftof the Pokemon center then you`ll see gates and trainers (you should have been there before).Now go around those gates until your at the water and the lady and the sighn that says something about Mt.Pyre then surf around the big mountain that looks like a rock and you should find a cave. Go in this is were you get lax incense and sea incence from falling down the right holes on the higher floors.

Anyway once your in go to the left then go south there will be a door go in and you`ll be outside.(ther are a few hidden items out there and you can catch meditite and duskull there.Then start going up you'll see Team Aqua walk through the center and theyll move out of there spots beat them up and go behind them you'll find somegrass on the right hand side there you can get Chemico.

Then you will find Archie at the top he'll say something about you then he'll say''but you`re to late comeon it's Slateport next fly to Slateport and go to the dock you'll see news reporters and fans everywhere talk to one of the newsreporters and you'll here Archie go in and he'll have stolen a submarine.

Go back to Lilycove and go up the steps then go all the way to the right and jump downthe little bumps until you see some more stairs then you'll see a team aqua member with some wailord go north then surf you'll find a cave go in you'll be in Team Aquas base find your way through the teleporters beat up this one guy at the end and then leave after listening to that guy then you're done with Lilycove.
