The growing popularity of hiking exposes mountain ranges to human pressure they have never known before. A trail hosting a few hikers a week erodes differently from one seeing several hundred pass through daily in summer. Leave No Trace isn't an administrative constraint — it's an ethic built collectively so that the landscapes that shaped us remain intact for those who come after.
The Principles That Change Everything
Staying on the marked trail, even when a shortcut seems obvious, limits erosion and protects fragile vegetation that can take decades to regrow at altitude. Packing out all your waste — including biodegradable items like fruit peels, which take months to decompose in the mountains and attract wildlife that gains nothing from it — remains the most basic gesture, and yet the most often neglected.
Managing human waste deserves a special mention: absent available dry toilets, bury your waste at least 20cm deep and a minimum of 60 metres from any watercourse, to avoid contaminating sources downstream.
"The mountain doesn't belong to us. We only pass through it, and our sole duty is to leave nothing behind."
Respecting Wildlife and Other Hikers
Observing wildlife from a distance, never feeding it or altering its natural behaviour, preserves a balance that decades of overuse have already weakened in many ranges. Silence, often overlooked, is an integral part of this ethic: the mountains are also a refuge for those seeking a calm that a portable speaker instantly destroys for kilometres around.
Finally, campfires, even where permitted, should remain the exception rather than the norm — a simple gas stove covers the same needs without leaving a black scar on ground that will take years to heal.
Travelling Light, an Ecological Act in Itself
Reducing the weight and bulk of your gear isn't just about walking comfort — it's an environmental act in its own right. Less gear means fewer resources extracted, processed and transported for every outing, and equipment chosen to last rather than replaced every season mechanically reduces the overall footprint of the practice.
Favouring second-hand or reconditioned gear, increasingly available through specialist resellers, extends the life of perfectly functional equipment that would otherwise end up in landfill over a simple change of ownership.
Leading by Example Rather Than Lecturing
Correcting a hiker who strays off the trail or leaves litter behind requires more tact than firmness. Experience shows a moralising remark more often puts people on the defensive than convinces them, while a simple question — "did you drop this?" — paired with a concrete gesture, almost always opens the door to genuine behaviour change.
"You never convince someone to respect the mountains by lecturing them. You convince them by walking ahead of them, in the respect you show it."
New hikers, often simply uninformed rather than ill-intentioned, are the most receptive audience for these principles — provided they're passed on with the same kindness you'd have wanted to receive yourself when starting out.
The Special Case of Wildlife in Winter
Mountain wildlife gets through winter in an extremely precarious energy balance, where every unnecessary expenditure can jeopardise survival until spring. A chamois or ibex that flees at a hiker's approach, even from a respectful distance, burns energy it won't easily replace under the snow — better to observe through binoculars from a fixed point than to try getting closer.
This caution applies particularly to off-piste winter activities, whose silent, fast presence startles wildlife far more than a hiker moving slowly and predictably.
These principles evolve with experience: what feels restrictive on your first outings quickly becomes second nature, to the point where hiking any other way becomes unimaginable.
