well first you have to surf east from lilycove city. if there are wailmer or wailord in the way then you have to go to mt. pyre. which if yopu don't know where it is it is a little to the left of lilycove. you have to surf south then and get to the entrance. go in and go forward about 7 steps and then turn left and go into the other entrance. go up the stairs outside of the cave and you will have to fight some team aqua people. at the top when you beat the last person(s) an old lady will give you a magma emblem. fly to lavridge towm and go up the cable car and then go down where the guy sells those cookies. Once you enter there an image will show up once you jump over 2 or 3 of those barriers. After the image go into the cave and keep going into the south entrances. You will see the boss and after you fight him and groudon disapears fly back to lilycove and surf northeast to this cave which is team aqua's hideout. The 2 people will be gone. you have to go through some warps to get to aqrchie. after that i believe that the wailmer or wailord should be gone. then just sail east to mosdeep and there you are. P.S if your in a hurry then use super or max repel to avoid Pokemon and surf there quicker.
Hope this helped.
You just have to surf to the right of Lilycove city. If you can't because wailord is in the way, you probably need to go to mt. Pyre. If you've already done that, then probably go Slateport and go to the place where the ships are. There should be a big croud outside the it. If nobody's there, don't bother going inside....
U need to have beaten team aqua at their base (there is a masterball there so grab it to catch the red pokemon latios), then go up the stairs to the pokemon store, then ho west jump the ledges and go towards the team aqua base and keep going use surf and keep going. I'm playing sapphire now, I've beat it 2 times and I'm now beating it with a swampert.
after u finished the gym,go to the space center ....u will find it in the right top most area...inside,u will have to battle with the magma gang..and in the end u will have to save steven and battle magma leader max.... after u r done,steven will give u HM Dive.,,,with that...go search for a huge dive area south of mossdeep...and u will find it ..go through that..and u will find sootopolis.
You first have to go to Mt. Pyre and get the orb from the old man up there. then go back to Lilycove and surf to the cave and beat everybody in there and collect your Master Ball. Go out and you can surf there.
You explore the dive spots and find sootopolis city and seafloor cavern.
Simply surf east of lilycove city.
the seventh gym in pokemon sapphire is in mossdeep city.
You have to beat the gym leader first... then you'll find them there.
Pokemon platinum is for DS but it is in snowpoint
Slateport City doesn't have a gym.
he is in stooptopolis city
MOSSDEEP CITY
Mossdeep City
the seventh gym in pokemon sapphire is in mossdeep city.
In Mossdeep city I think.....
In Pokemon Sapphire, Ruby and Emerald the 7th Gym that's located in Mossdeep City has Psychic type Pokemon.
In Mossdeep city. On the right side of the island. (On the 7th gym island)
You get it from Juan in the Sootopolis Gym after beating him. Then, you get Waterfall.
You get surf for beating your dads gym.
You must beat the MossDeep City gym to use the HM for Dive.
Go on to defeat the seventh gym in Mossdeep City, if you did not already catch Kyogre.
Go to sootopolis city for your next badge.
you have to go to sootipoolis city which is next to mossdeep city
