If you look at your pokenav look at Lilycove city, you will see water use surf move to the side then go all the way down then you are at Sootopolis city.
Hope this helped.
you have to use surf and go to sootopolis city from lilycove. then dive down and find the underwater cave.
After the player defeats the administrator boss of Team Magma at their hideout in Lilycove City, the boss flees on the submarine. The player should then go on to explore Mossdeep and Sootopolis. The boss is now in the Seafloor Cavern below Sootopolis.
The location to Wailord is to the far right and far down. The location of relicanth is underwater,border of sootopolis island, north of sootopolis island and little east of lilycove city.
You must surf there from Sootopolis City, Mossdeep City, or Lilycove city. You cannot surf there from Slateport city because there are ocean currents that prevent you from going East.
You go to cave near lilycove city and go until you find Boss of Magma team, and then you go to sootopolis city and you must go to cave of origin in sootopolis city, and you go until you find Groudon in Magma pool. Yeah, you must to take groudon to become your Pokemon, yeah yeah yeah!!!!

On sea routes, near Lilycove, Sootopolis and Mossdeep City, use DIVE, to go underwater then just move through the seaweed patches... Remember that they are rare so be patient...

It depends. If you are talking about the one of the coast of Lilycove,then you surf east to get to Mossdeep City. If you are talking about the one where Archie awakens Kyogre,then you need to go to Sootopolis City and talk to Steven.Then you will find out what to do.:D
