Sootopolis. You have to go through the whol Kyogre episode then the gym will open up. (Sootopolis is the white place you have to dive to get into.)
Gym 2 is Cerulean City, and the Gym Leader is Misty ("The Waterflowers of Cerulean City" is the Pokemon episode with Misty and her three sisters). To get to Cerulean City, you need to go through Mount Moon.
She wanted to become a gym leader back in her hometown but don't worry she comes back in an episode called a Pokemon mirage.
It's the one where they battle the gym leader with a raichu and ash tries to use a thunderstone on pikachu
It's either Episode 22 - Abra and the Psychic Showdown or Episode 24 - Haunter Versus Kadabra I think. :P.
In Pokemon Ruby, Sapphire, and Emerald, the player cannot battle the last gym until after the episode in the Cave of Origin. After Groudon/Kyogre have been defeated, the player can return to the gym in Sootopolis and fight the final gym leader.
