Pokémon Ruby and Sapphire/Route 126
Route 126 is a large, circular area with a dormant volcano at its center. There are a few trainers:
- Swimmer Brenda
- Goldeen (lvl. 35)
- Swimmer Barry
- Gyarados (lvl. 35)
- Swimmer Nikki
After you down the trainer, look for the ring of dark water encircling the volcano. Swim to the southern part of the ring and dive to find the entrance to Sootopolis City.
 Pokémon found
Relicanth is found underwater in Route 126. Though it is a fish Pokémon, it cannot be caught with a fishing rod. It is slightly tough to catch; 2 or 3 Ultra Balls might get wasted, and Net Balls and Dive Balls do not work well.
