defeat all the other gym leaders
actually there isn't 9 gym leader there is only 8 like the other ones. Actually, the 9th gym leader in heartgold and soulsilver would be the first gym leader in Kanto after you beat the elite four the first time, you can face the kanto gym leaders in any order.
After defeating Koga, who is the fifth gym leader in the Kanto Region, just move on to the next city. You can get the gym badges out of order, so just move on to a city that you haven't defeated yet. Save Cinnabar Island for last, though, because it definitely is the toughest gym.
The gym leader is not at the gym and that is why we cannot enter the gym.
Giovanni Is The 8th Gym Leader In Kanto, And He Is The Leader Of The Evil Organisation, Team Rocket.
Fuchsia city (Kanto) Cianwood city(Johto) Hearthome city(Sinnoh)
To get the Olivine City Gym leader to battle you, you have to go to the top of the lighthouse and help her heal a Pokemon by getting medicine from a man across the sea in Cianwood. The leader there, Chuck, is actually the fifth, and Jasmine is the sixth.
