The fifth route that Trainers from New Bark Town encounter, Route 33 is a short route that travels west to Azalea Town. This route is not very long, since Trainers have already traveled through Union Cave and passed Route 32 to reach this clearing. After exiting Union Cave through a small opening, the player will find a small clearing with a sign. After climbing down the stairs or jumping the ledge, the player can either go west or find a patch of tall grass where Pokémon from previous routes appear. By going west, the player will be able to find a Berry tree on which a PSNCureBerry grows, as well as a single Trainer, a Hiker, who can be battled. By continuing west, the player will finally reach Azalea Town, the next town on the Trainer's quest.
In Generation IV, Route 33 is a little different from before. It is now always raining, and the effects of the rain are effective during battles. There are also two Apricorn trees now in the place of the single Berry tree. The right-hand tree holds a Blk Apricorn, while the left-hand tree holds a Pnk Apricorn.
