Route 22

24 Pokémon can be caught at Route 22 in Kanto — highlighted on the map below.

Route 22 links Viridian City with the Pokémon League Reception Gate in western Kanto, winding past grass patches, a small hill, and a pond. The player's rival appears here twice for battle near the first grass patch: an optional early fight shortly after Oak's parcel is delivered, and a mandatory rematch once all eight Badges are in hand. A ledge along the route's southern edge makes the westbound trip one-way, with a narrow return path back to Viridian. In Pokémon HeartGold and SoulSilver, Giovanni can be seen abandoning Silver here.
