This will open the Cities_Skylines folder in the explorer. You can find the maps folder in the Steam installation folder under the following path:ĭ:\SteamLibrary\steamapps\common\Cities_Skylines\Files\MapsĪlternatively, you can right-click Cities Skylines in your Steam Library, then click Manage and Browse Local Files. In my case I installed all Steam games on hard drive 'D'. New maps are also included in every expansion, and you can find them in the installation directory. To do this, you first have to copy the map files into another directory.Ĭities Skylines ships with a handful of default maps, that you can play on right from the start. If you want to make changes to default maps in Cities Skylines, this will not work without further ado.
