You go to the east side of cinabar is by surfing there. There should be a cave. Defeat the playear thats there and then enter the cave. There should be a ladder in there just go up it. And the 7th gym shud be there. Good luck !
Blue is on Cinnebar but he just says he doesn't want to battle you until you get more badges.
