Route 23 (Japanese: ２３ばんどうろRoute 23) is the final numbered route in Unova. It is located in northeastern Unova and connects the Giant Chasm to Victory Road. It can only be accessed after the player has defeated Ghetsis in the Giant Chasm's deepest part.
The music that plays on this route features a slower, remixed version of the theme that plays in Professor Rowan's laboratory in the Generation IV games.
Bouffalant that appear in the tall grass can be found at level 56, and the three Amoonguss disguised as fake items appear at level 56; making them the highest leveled non-legendarywild Pokémon the player can legally obtain in any game prior to credits.
