Leave No Trace — a practical guide to the seven principles

Leave No Trace is a framework for decisions, not a claim that a visit creates literally zero impact. The seven principles help hikers, campers and sightseers reduce avoidable damage while adapting to the rules and ecology of a particular place.

The official principles are copyrighted guidance maintained by Leave No Trace. This article summarizes how to apply them; use the organization's current material and the land manager's rules for detailed practice.

1. Plan ahead and prepare#

Check permits, closures, weather, fire restrictions, water reliability, road access, group limits and waste requirements. Repackage food to reduce wrappers and bring containers for trash, hygiene products and pet waste.

Planning prevents improvisations that damage a place: illegal fire rings, overflow parking, abandoned gear and emergency shortcuts.

2. Travel and camp on durable surfaces#

Use established trails and sites where required. Durable surfaces can include rock, gravel, sand, dry grass and snow, but local guidance matters. Desert biological soil crust and alpine vegetation can look sturdy while being exceptionally vulnerable.

Do not cut switchbacks or widen a muddy trail by walking around every puddle. In popular areas, concentrating use on the established tread usually causes less total damage.

3. Dispose of waste properly#

Pack out food, packaging, hygiene products and every piece of trash. “Biodegradable” does not mean appropriate to leave. Human-waste practice varies by environment: some places use catholes, others require pack-out systems, toilets or special rules. Check before the trip.

Inspect rest stops and camp after packing. Small items—corners of wrappers, twist ties, foil and food scraps—are the usual leftovers.

4. Leave what you find#

Do not take cultural objects, rocks, plants or antlers. Do not carve, stack rocks, build furniture or improve a site. Photograph artifacts in place and report significant finds to the manager without broadcasting vulnerable coordinates.

A historic can is not automatically litter, and a cairn is not automatically official. When uncertain, leave it and ask.

5. Minimize campfire impacts#

A stove is usually the lower-impact cooking tool. Fires may be prohibited by season, location or permit even when a ring exists. Never burn plastic, foil, glass or food waste. If fires are allowed, follow local rules, use the permitted setup, keep it small and make it completely cold before leaving.

An old fire scar does not override a current restriction.

6. Respect wildlife#

Observe from a distance, never feed animals, secure food and trash, and control pets according to site rules. Wildlife that obtains human food can become aggressive or be killed as a management consequence. Trash storage is therefore a wildlife-safety practice, not housekeeping.

Give nesting, mating, feeding and wintering animals extra space. A photograph is not worth changing behavior.

7. Be considerate of others#

Keep group and speaker noise low, yield appropriately, avoid occupying viewpoints for long photo sessions, and manage pets. Use headphones only where they do not compromise awareness. Follow drone and commercial-photography rules.

Add one positive action without creating another impact#

Packing out one safe piece of litter is useful. Do not leave the trail, enter hazardous terrain or handle unknown waste for the sake of “leaving it better.” For a larger site, map the cleanup location with access, waste type and estimated effort. For changing conditions, add a dated visitor report to the mapped sight.

The principles work when they shape hundreds of small choices: where a boot lands, where food is stored, whether a fire is necessary and what leaves in the pack.
