Valley Windworks

28 Pokémon can be caught at Valley Windworks in Sinnoh — highlighted on the map below.

East of Floaroma Town beside Route 205 stands the Valley Windworks, a sizable power plant whose giant windmills turn wind into electricity for the region. During the events of Pokémon Diamond, Pearl, and Platinum, as well as Brilliant Diamond and Shining Pearl, the Team Galactic Commander Mars seizes the facility in a bid to exploit its energy output, only to be driven off by the player.
