Pokémon World Routes ← Route 3 Route 5 →

Route 4 is a short path in north Kanto from the eastern exit of Mt. Moon in the west to Cerulean City in the east. Though the official western terminus of Route 4 is at Route 3 south of Mt. Moon's western entrance, the western terminus is regarded by most to be Mt. Moon's eastern entrance.

Route description

From Mt. Moon, Route 4 travels to the east, swerving to the north and the south to avoid ledges along the route. The path turns north, then east near a large clump of trees surrounding a grassy area. To the east of this area is a ledge that separates Mt. Moon from Cerulean. By hopping down this ledge, the trainer cannot return to the previous towns until they travel through Diglett's Cave and use Cut on Route 2, or use Fly to return to the cities.

The majority of the route is fairly straight-forward as there is only one true way to proceed on the path and there are no trainers to battle (with the exception of the Lass on the highest hill on the route; however, she is reached only by way of the waterway that begins on Route 24).

Depending on the Generation, there are items, Move Tutors, or both along this path.

Differences among generations

Generation I to Generation II

The route was shortened significantly as the length between Mt. Moon and Cerulean was slashed in half, as was the grassy area. The TM was replaced with an HP Up and three trainers were added to the route.

Generation I to Generation III

Aside from cosmetic changes, two Move Tutors were added to the route. Located near the Mt. Moon portal, these tutors will teach a Pokémon the moves Mega Punch and Mega Kick.

In the Pokémon Special manga

Route 4 is visited in Gyarados Splashes In! and Raging Rhydon in the Red, Green & Blue chapter by Red and Misty. It has a Pokémon Center and is where Mt. Moon is located, a Moon Stone is found in this last place.
