victory road

Once you get in, you'll see a boulder. Use Strength to push that boulder to the ground switch on the right. Now head up the stairs, and go on until you see two other stairs between a trainer: one on the left and one on the right. Take the stairs on the right for a Rare Candy and TM02 - Dragon Claw. After getting the items, take the stairs on the left, and go up the ladder.

Go down and push the boulder onto the switch. Go up the stairs, and head east. If you choose to go down the stairs, you'll find TM37 - Sandstorm. No matter what you do, you'll need to go up the ladder located at the very end of this level. Before you take the ladder, be sure to pick up TM07 - Hail above the ladder.

Once you reach the next level, push the boulder you see up two times, and all the way west onto the switch. The Itemball you see contains TM50 - Overheat. Now head back to where you came from, and go up the stairs. Go all the way west, down the stairs, and all the way east. Push the boulder down the hole, and jump in with it. Push the boulder to the switch on the left. Head up the stairs, and then the ladder. Then you'll encounter a two-on-two Pokemon battle. Take the other ladder, go right, and you'll find a Move Tutor who teaches Double Team. Finally, you can exit Victory Road.

After all that, you'll reach the Indigo Plateau, where you'll fight in the Pokemon League.
