The Coastal Highway entrance to the Cinder Hills Coal Mine can be found at the far north side of the region, just north-west of the Abandoned Lookout, just north of Upper Falls and north-east of Rural Crossroads.
Cinder Hills Coal Mine is similar to Abandoned Mine No. 3. They both have long, dark tunnels that connect two regions together.
Air temperature inside the mine is quite warm, and, since no animals spawn inside the mine, it can serve as a safe, temporary base in which to rest.
The Cinder Hills Coal Mine, like all mines, is abundant in coal. Coal is a highly valuable item that is required to heat the furnace to forge items like arrowheads, Improvised hatchets, and Improvised knifes.
The mine is not long, however it has many dead ends and is quite tricky to navigate without any light source.
