Route 23 (Japanese: ２３番道路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.
Route 23 connects Victory Road with the Giant Chasm. It is a mountain-like road, with many mountainous features, such as ponds and crevasses. The northwest portion of the route features a puzzle involving Strength and Cut. There are narrow paths between trees and raised platforms, making it hard to navigate and find the right path.
After seeing it in the Cave of Being, Azelf can be found on the raised platform north of the area with the Strength rock puzzle.
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.
This route and Route 23 in Kanto both have the same name, and are the last routes before their region's respective Pokémon Leagues. However, the positions of Route 23 and Victory Road in relation to the Pokémon League in Kanto are inverted in Unova.
