Route 4

In Pokémon Black and White, Route 4 is a huge half-constructed road through a desert north of Castelia City. There are exits at the north and south. It starts off with a paved road which ends abruptly after fifty steps. Along the paved road are a number of large, half-done construction sites. To the west of the paved road by Castelia City's exit there is a large plot of deep sand and a cliff next to the ocean, with two Fishermen fishing there. To the north of the cliff-lined sea there is another half-done construction site. In the middle of the route, there are two paved roads; one that goes north towards Nimbasa City, and the other facing west and eventually north, leading to the Desert Resort.
