First, go through the first portal platform. Then go to the bottom left hand corner portal platform. Then just go up and down. If you can't go up, go down. If you can't go down, go up. You'll eventually get there without having to battle any trainers.
Good Luck!
Go up to the top of the lighthouse (the long way) until you reach Jasmine. She'll give you the assignment to go and get an antidote for Amphy. Surf south and west until you get to Cianwood. Talk to the guy in the pharmacy and he'll give you the secret potion. Go north to find suicune, then go back south to battle Chuck. After you have your fifth gym badge, head back to Olivine to give the potion to Jasmine. Amphy will be cured and she'll gladly battle you in the gym.
