Campfires can be created in adventurer mode by pressing g. Currently campfires do not require anything to build, although it has been indicated that in the future there will be more work involved in their creation. Walking into a tile containing a campfire is not possible, even for creatures immune to fire. Jumping over and even into a campfire is possible and harmless. Campfires can't be destroyed but will disappear on their own after few hours.

 Fortress Mode
It is possible to find campfires when embarking along with other structures that cannot be built like walls made out of cloth or leather. In these locations there will be no trees or plants at the start and all murky pools will have been removed. These campfires constantly produce smoke and do not go out on their own nor can they be removed by building over them or channeling out the ground beneath them effectively making them irremovable.
In previous versions, human and necromancer sieges will light campfires. This was turned off in the early 0.40 series.
