Kanto Route 23/Route description/Red, Blue, Yellow, FireRed, and LeafGreen/Southern segment

Heading north from the Pokémon League Front Gate, which houses the first Badge checkpoint, Route 23 heads northeast, passing through the first of many archways on the route as well as the second checkpoint. Northwest of this point is the second archway and the third checkpoint. The main path of the road then heads north, taking a slight northeast alignment as it approaches the third archway and the fourth checkpoint on the bank of a waterway that effectively separates the route into two halves.

Directly north of the fourth checkpoint is checkpoint five, in the shadow of archway four. Northeast of this location, past an island in the water that splits the channel into two, is the next archway/checkpoint. The route continues north, making landfall northeast of the sixth checkpoint.

In this area, Route 23 is dotted with grassy patches and boulders, creating a unique look not seen anywhere else in Kanto outside the. North of the scenery, the route encounters the seventh checkpoint underneath the final archway on the route.

Route 23 turns to the northwest, passing the final patch of grass on the road before returning to a north-south alignment several paces south of the final checkpoint. Just north of the checkpoint is the south entrance to Victory Road.
