Now you've collected all the badges you'll need to enter the Pokémon League. Go west to Route 22 and through the grass. As you walk through the route, you'll meet Gary once again.
After defeating Gary, continue on west.
Go over to the huge building at the end of the road. This is the Pokémon League gate, where eight guards will ask for your badges. You'll need to bring a Pokémon that knows how to surf and a Pokémon that knows Strength to get through the league route.
The building at the very end leads to Victory Road.
This is the final test for your Pokémon before you can enter the Pokémon League. This is a cavern with boulders you can push. What you need to do is move the boulders to target-shaped switches to remove blocks that are blocking your way. The switches will help you find the exit.
Somewhere in the cave, you'll find the legendary bird Pokémon, Moltres. Your Pokémon probably aren't strong enough to weaken it enough for catching, but if you still want to try, save the game before battling Moltres.
Once you reach the exit, you're finally out of the cave. Go north to Indigo Plateau.
Indigo Plateau and the Elite Four
In Indigo Plateau, you'll fight the top four Pokémon trainers in battle. You must defeat all four of them in succession. If you lose, you'll have to start all over. Make sure your Pokémon are trained to Level 60 or higher, and stock up on recovery items. Remember, once you enter the door leading to the Elite Four, there's no turning back. After defeating each trainer, make any necessary repairs with your recovery items.
Above all, good luck.

Having defeated the Elite Four, your Pokémon may be very
weak by now. You'll do fine with some recovery items. Gary has a
well-balanced team, so yours should be well balanced as well if you
want to beat Gary. Here's how to defeat Gary's
When you defeat Gary, you are the new champion. Professor Oak arrives and congratulates you on your victory and follows you to the next room. You and your Pokémon are now inducted into the Pokémon League Hall Of Fame.
