How do you get into the cave by lilycove city in Pokemon sapphire?

Answer 1

First you have to catch relicanth underwater (press L) and get a wailmer in sootopollis city and evOlve it at level forty. After you have both pokemon hm dive and hm surf and tm dig go to pacifilodg town and surf left to the lowest of the screen possible . When you get to a dark spot use dive then dive to the only place possible when you get to a Braille spot underwater use dive again to go up. You will be in a cave. Go to the back side of the wall and use dig. Go through the hole and all the way to the back side of it and press a where Braille is( note before you press a put your relicanth first in your team and warlord last.) you should see the screen shake. You have opened the door to the cave
