A lava-filled cavern
Caverns or Caves are commonly-found cavities in the Stone layer of a map. Many caverns have tunnels branching off and winding in other directions, some of which connect to the surface of the map creating natural entries to the cavern. Caverns can be quite deep, extending from the surface all the way to the Bedrock layer, which is impossible to break through. These caverns are randomly generated so no two of them will look exactly alike, making guides hard to be formed. It can sometimes be attached to natural dungeons.
In caverns it is expected to contain at least one one type of exposed ore block. Hostile mobs often spawn in naturally occurred caverns so it is advisable to bring along a weapon if on any difficulty other than peaceful.
Caverns can be useful as a starting point for creating player-made dungeons and other underground structures with. Since it is a natural cave, it can save quite a bit of time on trying to find ore. However, caverns could be quite deep, like a pit, so accidentally breaking into one from above could inflict a lot of fall damage. Players should be aware of the presence of lava as it is one of the main risk factors of exploring caverns, even on peaceful.
