look in the other places he could be
Groudon and Rayquaza are located in the Hidden Tower off of Route 47.
YOU CANT!!!!!!!!!!!!!!!!!!! Only in Emerald and Ruby.
in origin cave where u find kyogre in sapphire
He's where you left him in the Weather Tower, in the top floor in the top left corner. He'll tell you that there's some strange drought on a certain route. Fly to the route he tells you and search in the grass there to find Groudon.
First of all its spelled emerald. Anyway to find Groudon the legendary Continent pokemon Groudon follow these steps. 1. Defeat the elite 4. This is CRUCIAL! If you dont you cant catch him 2.Go to the weather institute(Where you fought team aqua on your way Fortree city) 3.Go to the 2nd floor and talk to the scientist in the back.He will say "There is a massive drought on route (random route) or something like that.Go to that route and enter a cave that wasnt always there. 4.Enter it and you will find another door.enter and you will find groudon. 5.You'll maybe want kyogre too so do everything the same but the guy at the institute will say rainfall and go to the specified route.(you may have to dive) you'll find a cave like you did with groudon.but it will hold kyogre instead. hope this helped.(i know its a little late)
To get groudon or kyogre you have to beat the Pokemon league then go to the weather institute {where you got castform or next to fortree city} and talk to the scientist upstairs to the left and he will say that there's a drought on a route,that's where groudon is. he is in a cave on that route. but you have to hurry because he will not be there all the time.
you cant get groudon only if you trade
Go to route 116 and search there and you'll find a entrance. go in it and there is groudon. Hint: go with lots of ultra balls and Pokemon which knows sing or hypnosis

no, you cant get a kyogre in Soalsilver and in Heartgold you cant get a groudon. :)
You find it in Route 224 using the Poke radar and there you go you've got it from Paul Myers
