Leave No Trace: The 7 Principles Every Camper Should Know
Leave No Trace is not just about picking up trash. It is a comprehensive ethical framework for minimizing human impact on natural areas. As outdoor recreation grows, the cumulative impact of millions of hikers and campers degrades trails, campsites, water sources, and wildlife habitat. The seven principles are practical guidelines that preserve the wilderness experience for everyone who comes after you. This guide explains each principle with specific, actionable techniques.
Principle 1: Plan Ahead and Prepare
Poor preparation leads to poor decisions in the field. Running out of food leads to cutting a trip short and trampling off-trail to find a shortcut. Getting caught in weather without gear leads to cutting live branches for shelter. Arriving at a full trailhead leads to parking on vegetation.
Check regulations before your trip: permit requirements, fire restrictions, group size limits, and camping restrictions. Plan your route to use established trails and campsites. Pack food in repackaged containers to minimize trash. Carry a map so you stay on trail. Preparation is the foundation that makes all other principles easier to follow.
Principle 2: Travel and Camp on Durable Surfaces
Durable surfaces include established trails, rock, gravel, sand, and dry grass. Fragile surfaces include cryptobiotic soil crusts (desert), wet meadows, and the area around water sources. Walk single-file on established trails, even if the trail is muddy. Walking around mud widens the trail and creates braided paths that scar the landscape.
Camp on previously used campsites whenever possible. In pristine areas without established sites, camp on rock, sand, or gravel at least 200 feet from water sources and trails. Spread tents and cooking areas to avoid creating a visible new campsite. Move camp every night in pristine areas to prevent lasting impact.
Principle 3: Dispose of Waste Properly
Pack out everything you pack in: all trash, leftover food, and hygiene products. If you carried it in, you carry it out. Burying trash does not work — animals dig it up and scatter it. Burning trash in campfires does not fully consume many materials and leaves residue.
Human waste in the backcountry must be deposited in a cathole: 6-8 inches deep, at least 200 feet from water, trails, and camp. In sensitive areas (alpine zones, deserts, high-use areas), pack out human waste using WAG bags. Toilet paper should be packed out in a sealable bag, not buried or burned. Strain dishwater and scatter it 200 feet from water sources.
Principles 4-5: Leave What You Find and Minimize Campfire Impact
Leave natural and cultural features undisturbed. Do not pick wildflowers, collect rocks, carve trees, or build structures. These seem minor individually but at scale across millions of visitors, they degrade the environment visibly. If everyone took one rock from a national park, the parks would be measurably different within a decade.
Campfires leave lasting scars. Use a lightweight camp stove for cooking instead of a fire whenever possible. If you build a fire, use existing fire rings, keep fires small, burn only dead and down wood smaller than your wrist, and burn all wood to ash. Scatter cooled ash away from camp. In many areas above treeline and in desert environments, fires are prohibited entirely.
Principles 6-7: Respect Wildlife and Be Considerate
Observe wildlife from a distance. Do not approach, feed, or follow animals. Feeding wildlife habituates them to humans, which ultimately leads to euthanasia when habituated animals become aggressive. Store food properly to prevent wildlife access. Give nesting and denning areas a wide berth, especially during spring and early summer.
Be considerate of other visitors. Yield to uphill hikers and stock animals on trails. Keep noise levels low, especially near camp and at water sources. Camp away from other groups when possible. Leave gates as you found them. Control pets at all times. The wilderness is a shared resource, and courtesy ensures everyone has a quality experience.
Frequently Asked Questions
Can I have a campfire in the backcountry?
Check local fire regulations first — many areas prohibit fires seasonally or permanently. If fires are allowed, use existing fire rings, keep fires small, burn only dead and down wood smaller than your wrist, and extinguish completely (drown, stir, feel for heat). A camp stove is always lower-impact than a fire.
How do I dispose of human waste in the backcountry?
Dig a cathole 6-8 inches deep, at least 200 feet from water, trails, and camp. Deposit waste, cover and disguise the hole. Pack out toilet paper in a sealable bag. In sensitive areas (alpine, desert, high-use), use WAG bags to pack out all human waste. Some areas require WAG bags by regulation.
Why can I not pick wildflowers or collect rocks?
Individual impact seems minor, but cumulative impact across millions of visitors is significant. National parks receive 300+ million visits per year. If even 1% of visitors picked one flower, that is 3 million flowers removed annually. Leave No Trace preserves the experience for everyone who follows.
Is it okay to feed wildlife?
Never. Feeding wildlife habituates animals to humans and human food. Habituated animals become aggressive, approach people for food, and are ultimately euthanized by wildlife managers. Even feeding birds and squirrels in the backcountry changes behavior patterns and can increase disease transmission.
