Leave No Trace, sometimes written as LNT, is a set of ethics promoting conservation of the outdoors. Originating in the mid-20th century, the concept started as a movement in the United States in response to ecological damage caused by wilderness recreation. [1] In 1994, the non-profit Leave No Trace Center for Outdoor Ethics was formed to create educational resources around LNT, and organized the framework of LNT into seven principles. [2]
The idea behind the LNT principles is to leave the wilderness unchanged by human presence.
By the 1960s and 1970s, outdoor recreation was becoming more popular, following the creation of equipment such as synthetic tents and sleeping pads. A commercial interest in the outdoors increased the number of visitors to national parks, with the National Park Service seeing a five-fold increase between 1950 and 1970, from 33 million to 172 million. [3] [4] Articles were written about the wild being “loved to death,” problems with overcrowding and ecological damage, and the need for management. [5] To solve this, regulations were imposed, including limits on group sizes and where camping was allowed. This was met negatively, with people writing that it took the joy and spontaneity out of wilderness recreation. [6] [7]
The focus was shifted towards education, with the National Park Service (NPS), United States Forest Service (USFS), and the Bureau of Land Management (BLM) training Wilderness Informational Specialists to teach visitors about minimal impact camping. In 1987, the three departments cooperatively developed a pamphlet titled "Leave No Trace Land Ethics". [8]
At the same time, there was a cultural shift in outdoor ethics from woodcraft, where travelers prided themselves on their ability to use available natural resources, to having a minimal impact on the environment by traveling through wilderness as visitors. [3] Groups such as the Sierra Club, the National Outdoor Leadership School (NOLS), and the Boy Scouts of America were advocating minimum impact camping techniques, and companies like REI and The North Face began sharing the movement.
In 1990, the national education program of Leave No Trace was developed by the USFS in conjunction with NOLS, alongside Smokey Bear, Woodsy Owl, and programs like Tread Lightly! geared towards motorized recreation. The Bureau of Land Management joined the program in 1993 followed by the National Park Service and U.S. Fish and Wildlife Service in 1994. [8]
The number of LNT principles varied widely during the 1990s, starting from 75 and dropping to 6 as more people had input and principles were condensed. [9] However, by 1999, the list was finalized as seven principles and has remained unchanged.

Since 1994, the Leave No Trace program has been managed by the Leave No Trace Center for Outdoor Ethics, a 501(c)(3) non-profit organization, dedicated to the responsible enjoyment and active stewardship of the outdoors worldwide. [11] Leave No Trace works to build awareness, appreciation and respect for wildlands through education, research, volunteerism and partnerships. The center also has a youth education initiative, Leave No Trace for Every Kid, which emphasizes asset development in youth through the lens of outdoor stewardship.
The center has partnerships with the National Park Service, the U.S. Forest Service, the Bureau of Land Management, the U.S. Fish and Wildlife Service, [12] US Army Corps of Engineers, and other partners such as colleges, universities, guide services, small businesses, non-profits and youth-serving organizations such as the Boy Scouts of America and the American Camp Association.
Over 20 percent of the organization's 2019 income went to three members of their board of directors. [13]
There are also formal Leave No Trace organizations in Australia, Canada, Ireland and New Zealand. [14]
While Leave No Trace is a widely accepted conservationist ethic, there has been some criticism. In 2002, environmental historian James Morton Turner argued that Leave No Trace focused "largely on protecting wilderness" rather than tackling questions such as the "economy, consumerism, and the environment", and that it "helped ally the modern backpacker with the wilderness recreation industry" by encouraging backpackers to purchase products advertising Leave No Trace, or asking people to bring a petroleum stove instead of building a natural campfire. [15]
In 2009, Gregory Simon and Peter Alagona argued that there should be a move beyond Leave No Trace, and that the ethic "disguises much about human relationships with non-human nature" by making it seem that parks and wilderness areas are "pristine nature" which "erases their human histories, and prevents people from understanding how these landscapes have developed over time through complex human–environment interactions". They posit that there should be a new environmental ethic "that transforms the critical scholarship of social science into a critical practice of wilderness recreation, addresses the global economic system...and reinvents wilderness recreation as a more collaborative, participatory, productive, democratic, and radical form of political action". They also write about how "the LNT logo becomes both a corporate brand and an official stamp of approval" in outdoor recreation stores like REI. [16]
The authors articulate their new environmental ethic as expanding LNT, not rejecting it all together, and share the seven principles of what they call 'Beyond Leave No Trace': [16]
In 2012, in response to critiques of their 2009 article, Simon and Alagona wrote that they "remain steadfast in our endorsement of LNT’s value and potential" but that they believe that "this simple ethic is not enough in a world of global capital circulation." They write that Leave No Trace "could not exist in its current form without a plethora of consumer products;" that "the use of such products does not erase environmental impacts;" and that LNT "systematically obscures these impacts, displacements, and connections by encouraging the false belief that it is possible to 'leave no trace'". [17]
Other critics of Leave No Trace have argued that it is impractical, displaces environmental impacts to other locations, "obscures connections between the uses of outdoor products and their production and disposal impacts" and have questioned how much the ethic affects everyday environmental behavior. [18] [19]
Appalachian Mountain Club (AMC) is the oldest outdoor group in the United States. Created in 1876 to explore and preserve the White Mountains in New Hampshire, it has expanded throughout the northeastern U.S., with 12 chapters stretching from Maine to Washington, D.C. The AMC's 100,000 members, its advocates, and supporters mix outdoor recreation, particularly hiking and backpacking, with environmental activism. Additional activities include cross-country skiing, whitewater and flatwater canoeing and kayaking, sea kayaking, sailing, rock climbing and bicycle riding. The Club has about 2,700 volunteers, who lead roughly 7,000 trips and activities per year. The organization publishes a number of books, guides, and trail maps.
Aldo Leopold was an American writer, philosopher, naturalist, scientist, ecologist, forester, conservationist, and environmentalist. He was a professor at the University of Wisconsin and is best known for his book A Sand County Almanac (1949), which has been translated into fourteen languages and has sold more than two million copies.
Philmont Scout Ranch is a ranch located in Colfax County, New Mexico, near the village of Cimarron; it covers 140,177 acres (56,728 ha) of wilderness in the Sangre de Cristo Mountains on the east side of the Cimarron Range of the Rocky Mountains. Donated by oil baron Waite Phillips, the ranch is owned and operated by the Boy Scouts of America. It is a National High Adventure Base where crews of Scouts and Venturers take part in backpacking treks and other outdoor activities. By land area, it is one of the largest youth camps in the world. During the 2019 season, between June 8 and August 22, an estimated 24,000 Scouts and adult leaders backpacked through the Ranch's extensive backcountry. That same year 1,302 staff were responsible for the Ranch's summer operations.
Camping is a form of outdoor recreation or outdoor education involving overnight stays with a basic temporary shelter such as a tent. Camping can also include a recreational vehicle, sheltered cabins, a permanent tent, a shelter such as a bivy or tarp, or no shelter at all. Typically, participants leave developed areas to spend time outdoors, in pursuit of activities providing them enjoyment or in a form of educational experience. Spending the night away from home distinguishes camping from day-tripping, picnicking, and other outdoor activities.
Campsite, campground, and camping pitch are all related terms regarding a place used for camping. The usage differs between British English and American English.
NOLS is a non-profit outdoor education school based in the United States dedicated to teaching environmental ethics, technical outdoor skills, wilderness medicine, risk management and judgment, and leadership on extended wilderness expeditions and in traditional classrooms. It was previously known as the National Outdoor Leadership School, but in 2015, this label was retired in favor of the independent "NOLS". The "NOLS" mission is to be the leading source and teacher of wilderness skills and leadership that serve people and the environment. NOLS runs courses on six continents, with courses in a variety of wilderness environments and for almost any age group.
Backpacking is the outdoor recreation of carrying gear on one's back while hiking for more than a day. It is often an extended journey and may involve camping outdoors. In North America, tenting is common, where simple shelters and mountain huts, widely found in Europe, are rare. In New Zealand, hiking is called tramping, and tents are used alongside a nationwide network of huts. Hill walking is equivalent in Britain, though backpackers make use of a variety of accommodation, in addition to camping. Backpackers use simple huts in South Africa. Trekking and bushwalking are other words used to describe such multi-day trips.
The Maroon Bells are two peaks in the Elk Mountains, Maroon Peak and North Maroon Peak, separated by about half a kilometer. The mountains are on the border between Pitkin County and Gunnison County, Colorado, United States, about 19 kilometres (12 mi) southwest of Aspen. Both peaks are fourteeners. Maroon Peak, at 4,317 metres (14,163 ft), is the 27th highest peak in Colorado. North Maroon Peak, at 4,273 metres (14,019 ft), is the 50th highest. The view of the Maroon Bells to the southwest from the Maroon Creek valley is very heavily photographed. The peaks are located in the Maroon Bells–Snowmass Wilderness of White River National Forest. Maroon Bells-Snowmass Wilderness was one of five areas in Colorado designated as wilderness in the original Wilderness Act of 1964. The Wilderness area surrounds the extremely popular Maroon Bells Scenic Area, which is a major access point for Wilderness travel.
Golden Ears Provincial Park is a 555.9 square kilometres (214.6 sq mi) provincial park in British Columbia, Canada. It is named after the prominent twin peaks, which are commonly referred to as Golden Ears. The park was originally part of Garibaldi Provincial Park but was split off as a separate park in 1967. The area was logged extensively in the 1920s by the Lougheed and Abernathy Logging Company. Many recreational attractions are found within the park. Golden Ears Provincial Park is a protected area that contains many endangered species of flora and fauna.
Tread Lightly! is a nonprofit organization based in Centerville, Utah, whose mission is to promote responsible recreation through stewardship, education and communication. It was started as a campaign to address impacts from off road vehicles by the United States Forest Service in 1985, and became a nonprofit in 1990.
Matia Island is an island in the San Juan Islands of the U.S. state of Washington. The island's entire 145 acres (59 ha) comes under the protection of the U.S. Fish and Wildlife Service and is cooperatively managed by the Washington State Parks and Recreation Commission as Matia Island Marine State Park. Matia Island is a National Wildlife Refuge, part of the San Juan Islands National Wildlife Refuge. A 2-acre (0.81 ha) camping area around Rolfe Cove is managed as a State Marine Park by the Washington State Parks and Recreation Commission under an agreement dating back to 1959. Pets, wood collecting, and campfires are not allowed on the island. Except for the Wilderness Loop Trail and the campground, all areas above the high tide line are closed to the public.
Trail ethics define appropriate ranges of behavior for hikers on a public trail. It is similar to both environmental ethics and human rights in that it deals with the shared interaction of humans and nature. There are multiple agencies and groups that support and encourage ethical behavior on trails.
Recreation ecology is the scientific study of environmental impacts resulting from recreational activity in protected natural areas. This field of study includes research and monitoring assessments of biophysical changes, analyses to identify causal and influential factors or support carrying capacity planning and management, and investigations of the efficacy of educational, regulatory, and site management actions designed to minimize recreation impacts. These ecological understandings of environmental impacts of outdoor recreation is critical to the management of recreation, ecotourism and visitation to natural spaces. Recreation ecology research has looked at the ecological impacts of hiking, camping and other outdoor recreation activities where the use and visitation is concentrated. As outdoor recreation shows increasing participation globally, questions and concerns are raised to which these can be managed sustainably with minimal impact to the environment.
Sykes Camp is located 10 miles (16 km) from the Pfeiffer Big Sur State Park trailhead along the Pine Ridge Trail.

The terms woodcraft and woodlore denote skills and experience in matters relating to living and thriving in the woods—such as hunting, fishing, and camping—whether on a short- or long-term basis. Traditionally, woodcraft pertains to subsistence lifestyles, with implications of hunting-gathering. In more recent times, and in developed countries, it relates more to either outdoor recreationalism or survivalism.
The Dinkey Lakes Wilderness is a federally designated wilderness area located 45 miles (72 km) northeast of Fresno, in the state of California, United States. It comprises 30,000 acres (12,141 ha) within the Sierra National Forest and was added to the National Wilderness Preservation System by the California Wilderness Act of 1984. Elevations range from 8,200 feet (2,500 m) to 10,619 feet (3,237 m). Recreational activities in the wilderness include day hiking, backpacking, horseback riding, fishing, rock climbing and cross-country skiing.
The Phillip Burton Wilderness is part of the 111 sq. mile (288 km2) Point Reyes National Seashore located about 20 miles (32 km) northeast of San Francisco, California. Total wilderness land is 33,373 acres which includes a roadless "potential wilderness" area of over 8,000 acres (32 km2) and is one of only three designated wilderness along the California coast, the others being the King Range Wilderness and the Rocks and Islands Wilderness. The National Park Service manages the wilderness.
The Panther Den Wilderness is a 1,195-acre (4.84 km2) parcel of land listed as a Wilderness Area of the United States. It is located within the Shawnee National Forest in Union County in the U.S. state of Illinois. Panther Den Wilderness is the smallest of eight Wilderness areas in Illinois. The other seven are Bald Knob Wilderness, Bay Creek Wilderness, Burden Falls Wilderness, Clear Springs Wilderness, Crab Orchard Wilderness, Garden of the Gods, and Lusk Creek Wilderness. All Illinois Wilderness areas are located in Southern Illinois.
BurroCross is self-reliant (unsupported) backcountry travel on foot in the company of a burro where, similar to Overlanding the experience of the journey itself is the principle objective. BurroCross is a non-competitive sport or recreational activity that proceeds at a walking pace and is centered on utilizing the overland capabilities of burros for companionship and sharing the burden of carrying the gear necessary to sustain the journey. The burro and the person progress through the journey and the experience as a team, side-by-side, therefore the burro is not ridden. The term "BurroCross" is a unique play on words that combines "burro" with the notion of cross-country travel, and it is also a nod to the familiar cross-shaped marking down the back and across the shoulders of most burros.
