Pinwheel Forest is a forest in Unova which lies between Nacrene City and Castelia City, at the east end of the Skyarrow Bridge.
In Pokémon Black and White, Rumination Field, home of the Legendary Pokémon Virizion, is located deep in the forest. However, in order to access this area, the player must have first encountered Cobalion, who resides in Mistralton Cave.
In Pokémon Black 2 and White 2, Virizion no longer resides here, instead taking residence on Route 11. The forest can only be visited after the player enters the Hall of Fame. Gorm of the Seven Sages can be found here while investigating with Cheren.
Due to the presence of a Moss Rock, Eevee can evolve into Leafeon here.
