Groudon is in the Cave of Origin, in Sootopolis City. Only in Ruby version. Kyogre is in the Cave of Origin in Sootopolis City, in Sapphire only.
Well, I know for sure that in Ruby version, Groudon is in there.
you need seven badges to enter the cave. to do it, go to sootopolis city and talk to steven who will then lead you to the cave
