Route 22 (Japanese: ２２番道路Route 22) is a route in central Kalos, connecting Santalune City and Victory Road. The route is also known as Détourner Way (Japanese: デトルネ通りDétourner Way).
North of the route, a race track can partially be seen. Based on NPC statements, it can be surmised as a track for Rhyhorn racing. Opposite the entrance to Victory Road, there is a series of ledges which provides a shortcut to Santalune City. In the south of the route, there is a river and waterfall which leads to the Chamber of Emptiness and other Trainers.
Despite a couple of Trainers on this route being only accessible by the use of Waterfall, which isn't possible outside of battle until the player has all eight Badges, the levels of these Trainers' Pokémon are closer to the NPC Pokémon levels around the point in the game when the player becomes able to use Surf outside of battle after their third Badge.
Détourner is a French verb (infinitive mode, present tense) that means "to divert", "to reroute", "to redirect", "to change course". The prefix dé- modifies the meaning of the verb tourner (meaning "to turn") to give it the antonymous meaning. Therefore, détourner means "to turn in the other direction than the one that was planned". It is possible the route was named this because the player is denied access to Victory Road the first time they can enter this route and so must turn around.
