Sometimes, and the deciding factor is ground durability rather than personal preference. Hiking off trail is reasonable on rock, gravel, snow and dry grass, and genuinely damaging on desert crust, alpine tundra and wet ground, with local rules overriding both.
One act is worse than all the others, and it is cutting switchbacks. Our guide to planning a hiking route covers working out in advance which kind of country you are entering.
Quick Answer
On durable surfaces, spreading out does less harm than concentrating onto a new path. On fragile ground, a single line of footprints becomes a permanent trail nobody planned. Check the rules at the trailhead, never cut a switchback, and treat mud on the trail as part of the trail.
Key Takeaways
- Ground type decides this more than anything else.
- Rock, gravel, sand, snow and dry grass tolerate foot traffic well.
- Desert soil crust, alpine tundra and wet meadows do not.
- Cutting switchbacks creates a channel that water then erodes for years.
- Stepping off to pass or to photograph is how trails get wider.
- Some areas require staying on trail and some encourage dispersal.
- Off-trail travel is also a navigation and exposure decision, not only an impact one.
| Ground type | Off-trail travel | Why |
|---|---|---|
| Bare rock and slabs | Durable | Nothing living to damage |
| Gravel, scree, sand | Durable | Already moving, no vegetation to crush |
| Snow | Durable | Melts and leaves nothing behind |
| Dry grass, established turf | Reasonably durable | Recovers, provided use is spread out |
| Desert biological soil crust | Very fragile | A living surface, and recovery takes years |
| Alpine tundra and cushion plants | Very fragile | A short growing season means slow repair |
| Wet meadow and boggy ground | Very fragile | Footprints become channels immediately |
| Streambanks and riparian edges | Very fragile | Damage feeds straight into the water |
The Answer Depends on the Ground
Leave No Trace guidance splits travel into two situations, and understanding the split resolves most of the confusion.
On established trails, stay on the trail and concentrate the use. The tread already exists and the damage is already done, so keeping everybody on it protects everything either side.
Off trail on durable surfaces, spread out instead. A party walking single file across gravel starts a path, while the same party walking abreast leaves nothing.
That reversal surprises people. On the trail you follow each other, and off the trail on durable ground you deliberately do not.
The instruction that never changes is the one about fragile ground, where the answer is simply to avoid it.
Cutting Switchbacks Is the Worst Version
Of everything in this article, this is the one with a physical mechanism you can watch happen.
A switchback exists to take a trail across a slope rather than up it, because a path running straight downhill becomes a watercourse. Cutting the corner makes exactly that.
Once a shortcut exists, rain follows it, and running water removes soil far faster than feet do. The channel deepens, the slope above destabilizes, and the original trail starts to fail at the corner.
It also gets used. A visible shortcut invites the next person, so a single act becomes a route, and repairing it is real trail crew work rather than a morning’s raking.
The saving is a few seconds of walking. It is the clearest cost-to-benefit mismatch on any trail.
Stepping Off, and Why One Person Matters
This is the everyday version, and it is where most trail widening actually comes from.
Stepping off the edge to let someone pass, to take a photograph from a slightly better angle, or to walk beside a companion all put weight on the vegetation holding the trail edge together.
The honest accounting is that one person does not matter and a thousand do. Every widened trail was widened one considerate step at a time.
Mud is the specific case worth naming. Walking around a wet section is what turns a narrow path into a braid of parallel routes, and walking through it is correct even though it is unpleasant.
Our note on mountain bike trail etiquette explains that braiding mechanism in detail from the riding side, and it works identically on foot. Gaiters and shoes you are willing to get dirty solve most of the reluctance, and our roundup of hiking gaiters covers that.
Fragile Ground You Cannot See
Some of the most easily damaged surfaces do not look like anything at all, which is how the damage gets done by people who would have avoided it.
Biological soil crust in arid country is the clearest example. The dark crumbly surface between desert plants is a living community, it holds the soil against wind and water, and a single footstep breaks it.
Recovery there runs in years rather than seasons. Desert parks post signs about this precisely because the surface reads as bare dirt to a visitor.
Alpine ground has a different version of the same problem. A short growing season means a crushed cushion plant does not simply regrow next month.
Wet meadows show damage instantly and hold it. A footprint in saturated ground is a depression that fills with water and widens.
The practical rule is to treat anything that looks specialized as fragile, and to read the trailhead signage in unfamiliar country rather than generalizing from home.
That signage is worth reading rather than skimming, because it usually explains why rather than only what. A sign that names the surface it is protecting teaches you to recognize the same ground somewhere without a sign.
Rules, and the Safety Half
- Read the signs at the trailhead. Requirements vary by area and by season.
- Assume stay-on-trail in heavily used places. Popular parks frequently require it outright.
- Expect the opposite in some wilderness. Dispersal is encouraged where trails do not exist.
- Tell someone if you are leaving the trail. A route description stops being useful once you leave it.
- Carry navigation you can use without a screen. Off-trail travel is where people get lost.
- Expect slower going and more exposure. Terrain, vegetation and loose ground all cost time.
- Check yourself afterward. Off-trail travel means more contact with vegetation.
The navigation point is the one people underestimate. Our guides to reading a topographic map and navigating without GPS cover the skills off-trail travel actually requires, and our roundup of handheld GPS units covers the hardware.
Our guide to what to do if you get lost hiking covers the situation this raises the odds of, and our note on checking for ticks after a hike covers the last item on that list.

Frequently Asked Questions
Is it OK to hike off trail?
Sometimes, and it depends on the ground and the local rules. Rock, gravel, sand, snow and dry grass tolerate foot traffic, while desert soil crust, alpine tundra, wet meadows and streambanks do not. Many popular areas require staying on the trail regardless.
Why is cutting a switchback such a problem?
Because a path running straight down a slope becomes a watercourse. Rain follows the shortcut, and running water removes soil far faster than feet do, so the channel deepens and the original trail starts failing at the corner. The shortcut also invites the next person.
Should my group walk single file off trail?
On durable ground, no. Walking abreast spreads the impact so no single line of footprints becomes a path. That reverses the instruction for established trails, where single file keeps everyone on the existing tread and protects both edges.
What about walking around a muddy section?
Go through it. Walking around is what turns one path into several parallel ones, and each detour widens the damage a little further. Gaiters and footwear you are willing to get dirty remove most of the reason people avoid it.
What is biological soil crust?
A living surface layer in arid country, made up of organisms that bind the soil and protect it from wind and water erosion. It reads as bare crumbly dirt to a visitor, a single footstep breaks it, and recovery runs in years rather than seasons.
How do I know what the local rules are?
Read the trailhead signage, and check the managing agency’s page before an unfamiliar trip. Requirements differ between areas and sometimes by season, and a rule that applies at home may be the opposite of the one where you are going.
Is off-trail travel more dangerous?
Generally yes, for reasons unrelated to impact. Navigation is harder, terrain is slower and less predictable, a route description you gave someone stops matching where you are, and contact with vegetation increases. Those are separate reasons to plan it properly rather than drift into it.
Does stepping off the trail to let someone pass count?
It contributes, and it is also the polite thing to do, so the practical answer is to step onto something durable where you can. Rock, gravel or bare ground rather than the vegetated edge, and back on the tread as soon as they have gone by.
