A campfire is a fire lit at a campsite, to serve the following functions: light, warmth, a beacon, an insect and/or apex predator deterrent, to cook, and for a psychological sense of security. In established campgrounds they are usually in a fire ring for safety. Campfires are a popular feature of camping, particularly among organized campers such as Scouts or Guides. In some regions it is called a bonfire, especially when it is of a very large size.
