Cities Skylines Maps Guide — Every Map, the Editor & Custom Maps
Cities Skylines maps explained: the base maps in CS1 and CS2, the map editor, the Steam Workshop custom maps (including the famous Boston map), and how to use custom maps.
Cities Skylines Maps Guide — Every Map, the Editor & Custom Maps
The short version: Cities Skylines ships with ~10 built-in maps (CS1 and CS2 each), but the map editor + Steam Workshop are where the real map library lives — tens of thousands of custom maps, including the famous Boston map (a meticulous real-city recreation). Custom maps install in one click via the Workshop.
This guide covers built-in maps, the editor, and custom maps.
Built-in Maps
- CS1: Ships with ~10 maps (Green Hills, Diamond Coast, Grand River, etc.) across different climates/tiles.
- CS2: Ships with ~10 base maps (River Delta, Twin Mountain, Barrier Island, etc.) with the game's new climate/terrain systems.
- Map tiles: Both games let you unlock additional buildable tiles as the city grows (the starting tile + expansions).
The built-in maps are fine starting points, but the Workshop is the real map source — thousands of community maps for free, one-click install.
The Map Editor
- CS1: A full terrain editor (paint terrain, water, resources, roads) — the tool that created the massive custom-map library.
- CS2: The editor was reworked; map creation is more involved (the community built tools around the new editor). The Workshop supports CS2 maps.
- How it works: Build a terrain → save as a map → publish to the Workshop (or use locally).
Custom Maps (Steam Workshop)

- Installing: Subscribe on the Workshop → the map appears in the New Game map list. One click.
- The famous ones: The Boston recreation (a meticulous real-city map, among the most-subscribed CS maps), plus recreations of other real cities and fictional masterpieces.
- Why they matter: "Cities skylines map" searches usually lead to the Workshop — real-city maps and challenge maps are the community's pride.
