A campfire is a controlled outdoor fire used for cooking, warmth, or ceremonial or recreational purposes. They can be built using various materials, such as wood, charcoal, or propane. Campfires are often associated with camping and outdoor activities, but can also be found in other settings such as parks and beachside areas. Building a campfire requires a fire pit or ring and a supply of combustible materials. It is important to follow local fire safety regulations and guidelines when building and maintaining a campfire.
