From Rust Wiki
Rust can be a very difficult game to navigate, as there is no UI map or in-game sign/roadway markings. There are however several community resources that players have made that might help you in navigating this new world.
Interactive maps[edit | edit source]
|rustmapmarks.com||Interactive map tool, mark locations, draw areas, leave notes, place labels, share your map, position locator, multiple maps, ingame map overlay tool.|
|rustmap.net||Coordinate locator, Zoom in and out, private and public markers/lines/shapes which you can save and edit live, multiple maps and layers.|
|K3X HD Map||High Resolution Map. Some Errors because of image-stitching, positions are not perfect. Plan is to Create a Map like rustmap.net but in HD, with radiationzones and lootspawns. (See Discussion)|
