Pokémon Gold and Silver/Blackthorn Gym

If you can't get inside the gym, it's probably that you didn't fight Team Rocket at the Goldenrod City Radio Tower yet.

The Gym has boulders like in the Ice Cave, when you go up to Level 2, there are two boulders, you can only push 1 of them into the hole though, to do thispush the one on the right up two, then push the left one into the hole, it doesn't do anything so go south and battle the Cooltrainer♀. When you get past her, push the far right block down all the way, then move the other one up 9 places then to the right, now for the final Boulder, battle the Cooltrainer then push the rock all the way to the right then push the other one down.

When you beat Clair, she says you have to go to Dragon's Den for a test before you get the final badge.
