Campfire Safety: Rules, Site Choice and Leave No Trace

The golden rules of campfire safety

Fire is one of the most valuable tools in the outdoors: it cooks food, purifies water, dries clothes and keeps you warm. It is also the one tool that can destroy a forest, a home or a life if it gets away from you. Almost every escaped campfire can be traced back to a handful of avoidable errors: lighting a fire during a ban, choosing a bad site, building it too big, leaving it alone or not putting it out properly.

Is a campfire allowed? Fire bans and danger levels

Before you think about wood or tinder, find out whether a fire is permitted at all. Rules vary enormously between countries, regions, land types and seasons, and they can change from one day to the next during dry spells. There is no universal rule, so always check the current local situation.

• Landowner permission: in many countries, lighting a fire on private land requires the owner's consent, and in public forests fires are often limited to designated sites.
• Protected areas: national parks and nature reserves frequently restrict fires to designated fire rings or ban them completely.
• Seasonal bans: many regions issue temporary fire bans or restrictions during dry, hot or windy periods. These can apply even to camping stoves or charcoal in some places.
• Access rights: countries with broad access rights, such as Scotland or the Nordic countries, still expect responsible behaviour and apply fire bans in dry conditions.

Germany, for example, generally prohibits open fires in and near forests outside approved sites under state forest laws; our guide to wild camping rules in Germany explains the background.

Most countries publish a daily fire danger rating through their weather or forestry services, usually on a scale of about five levels. The names and thresholds differ, but the logic is similar. Treat the table below as a general guide, not as a legal rule: the official local rating and any ban always take precedence.

Choosing a safe fire site

The safest fire site is one that already exists. An established fire ring or fire pit concentrates the impact in one place and has usually been placed with some thought. If there is none and fires are allowed, choose the site carefully as part of your overall camp site selection.

What to look for

• Bare mineral soil, sand or gravel. These do not burn. Forest litter, humus and peat do, and can smoulder underground for days.
• No roots. Tree roots can carry fire underground and resurface metres away.
• Nothing overhead. Check for overhanging branches, dead limbs and dry foliage above the site.
• Distance from camp. Keep tents, tarps, hammocks and gear well away: synthetic fabrics melt and burn easily.
• Sheltered, but not enclosed. A spot out of the wind is good; a hollow full of dry leaves is not.
• Water nearby. A site close to a stream or lake makes extinguishing easier, but do not build on the bank itself, where soil and vegetation are sensitive.

Wind: the most underestimated danger

Wind feeds a fire with oxygen, pushes flames sideways and carries sparks and embers far beyond the fire ring. Glowing embers can travel tens of metres in a strong gust and land in dry grass or forest litter. Many escaped campfires happened on days when the fire danger was only moderate but the wind picked up.

As a rule, if the wind is strong enough to move small branches constantly or blow dust and leaves around, it is too windy for an open fire. If the wind rises while your fire is burning, let it burn down, stop adding wood and extinguish it early. Build fires on the lee side of natural windbreaks and keep them low: a star fire or Dakota hole throws fewer sparks than a tall teepee.

Quick wind check: watch the smoke of the first minutes. If it rises steeply and drifts only slightly, conditions are fine for a small fire. If it lies flat along the ground or changes direction every few seconds, let the fire burn down and put it out.

Fire rings, fire pans and mound fires

Where you build the fire matters as much as whether you build it. Leave No Trace principles recommend using existing fire rings where they exist, and otherwise using a method that leaves no mark: a fire pan or a mound fire.

Existing fire rings

Use them if present. Do not build new stone rings next to existing ones: every ring is a permanent scar. Keep the fire inside the ring and do not make it larger than the ring allows.

Fire pans and fire bowls

A metal fire pan or fire bowl raised slightly off the ground keeps heat away from soil and vegetation and makes it easy to remove every trace of ash. Lightweight folding fire pans exist for backpacking. On sensitive ground, set the pan on a layer of mineral soil or sand to protect the ground from heat.

Mound fires

Where fires are permitted but no ring exists, you can build a mound of mineral soil or sand (from a place already disturbed, like a root ball or stream bar) about 15–20 cm thick on a flat surface such as a groundsheet or a flat rock, and build the fire on top. Afterwards, scatter the cold ash and return the soil to where it came from.

Keeping the fire small and under control

A small fire is safer, uses less wood and is more pleasant to cook on. Most bushcraft tasks need a fire no larger than about 50–60 cm across. Use the firewood calculator to gather what you need before you light, so you do not wander off for more while the fire burns.

• Never leave the fire unattended, not even for a few minutes. Wind can rise quickly.
• Keep water, sand or a shovel at hand from the moment you light the fire.
• Feed small pieces. Large logs burn for hours and are difficult to extinguish.
• Do not burn rubbish. Plastic, cans, glass and foil do not burn cleanly, release toxic fumes and leave debris. Food scraps attract animals.
• Do not use accelerants. Petrol and similar liquids can explode in a fireball. Use proper tinder and feather sticks instead.
• Stop feeding the fire early. Let it burn down to ash about an hour before you want to leave or sleep.

Use only dead and downed wood where collecting is allowed, never cut living trees, and consider carrying firewood from outside only if it is permitted: in some regions, moving firewood is restricted to prevent the spread of tree pests and diseases. For campfire cooking, a small bed of coals is all you need.

How to put out a campfire: drown, stir, feel

A campfire is only out when every ember is cold. Embers buried in ash can stay hot enough to reignite for many hours, sometimes even a day or more, and a breeze can bring them back to life after you have left. The widely taught method is simple: drown, stir and feel.

How much water? Far more than most people think: typically several litres for a small fire, more for a larger one. If water is scarce, use mineral soil or sand, mixing it thoroughly into the embers and stirring, but do not simply bury the fire: embers under soil can smoulder unseen and reignite. Never leave until the site is cold to the touch.

What "out" looks and feels like

• No steam, no hiss when you pour the last water and stir.
• Ash is a grey, wet paste, with no dry, fluffy pockets and no red specks when you turn it over.
• Half-burnt wood is black and wet on all sides, and you can hold it in your bare hand.
• The ground around the ring is cool when you press your palm on it, including under the stones.

Leave No Trace: fires without a footprint

The Leave No Trace principle "minimise campfire impacts" asks you to consider whether you need a fire at all. A stove is often more efficient for cooking and leaves nothing behind. When you do make a fire, the goal is that the next visitor cannot tell you were there, except at an established fire ring.

• Use existing rings or fire pans, and never build new rings where one exists.
• Burn wood completely to ash. Half-burnt logs are unsightly and hard to disperse.
• Scatter cold ash widely away from the site, once it is cold, unless you used a fire ring.
• Restore the site: return mineral soil, replace sod, scatter unused firewood naturally.
• Pack out everything, including foil, food scraps and anything that did not burn.

Where legal and appropriate, these practices protect soils, vegetation and wildlife. In areas with many visitors, established sites concentrate the impact and keep the rest of the landscape untouched. Good camp setup and a considered kit list make low-impact fires much easier.

Campfire safety with children and groups

Campfires are a highlight for children, and learning fire skills early builds confidence and respect. But children move quickly, underestimate heat and do not see danger in glowing embers. Clear rules and constant supervision make the campfire safe and fun.

In groups, assign a fire keeper who is responsible for the fire and its extinguishing, and a place where water and first aid are kept. A first aid kit should include burn dressings, and everyone should know the emergency number for the country you are in.

What to do if your campfire gets out of control

If a fire escapes the ring, act quickly but never put yourself or others in danger. A small ground fire of a square metre or two can sometimes be put out with water, soil or by beating it with a green branch or a wet jacket. If it spreads beyond that, or if flames reach bushes or trees, stop fighting it.

• Get people to safety first. Move away from the fire, upwind and downhill where possible, toward roads, water or cleared areas.
• Call the emergency number immediately: 112 in Europe, 911 in the US and Canada, 999 in the UK. Give your location as precisely as possible; the navigation skills and a map or phone GPS help here.
• Do not try to outrun a fire uphill. Fire spreads faster uphill.
• Report even small incidents you managed to put out if there is any chance it is smouldering underground.

The best emergency plan is prevention: fire bans respected, good site, small fire, water ready, never unattended, fully extinguished. Pair this guide with fire in wet weather and our other fire guides to build fires that are useful and safe.
