This route can be crossed in three different ways. On the top path, there is only one Trainer, Swimmer Katelyn. The middle path has the most Trainers, and the bottom path contains several items for the player to collect.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Trainers with a Vs. Seeker by their names, when alerted for a rematch using the item, may use higher-level Pokémon.
Trivia
This route is the only instance where an opposing Trainer in the water uses a Pokémon that cannot fly or reside in water, as Swimmer♀ Katelyn uses a Medicham.
