Trainers must return to the Falantr Docks and present their full badge cases to the guards on duty in order to access this long and tiring ocean route. A ferry service does run between the docks and Adar Zilira, but the Pokémon League requires trainers to cross the route on their own as a test of strength. Tough wild Pokémon are prolific here, as are other aspiring champions making their way north.
