After the sixth badge, you have to travel south from Fortree city. This route will have many trainers to battle, and is pretty long. Once you finish it, you will be in Lilycove city. There are a lot of Team Aqua memers there. Talk to all of them and you'll get an idea where to go. Hope I helped! :)
