An injured hiker who can no longer walk several kilometers from vehicle access poses a problem a first aid kit alone doesn’t solve. What happens when nobody in the group has ever practiced this before actually needing it? Building an improvised stretcher with two sturdy poles and clothing or a tarp is a simple skill, provided you also know when not to move the person at all.

- Suspected spinal injury changes the entire method: immobilizing the head becomes the priority, before even thinking about moving the rest of the body

What materials go into building an improvised stretcher?
Two long, rigid poles (trekking poles, sturdy branches, disassembled tent poles) form the basic frame, over which a carrying surface gets stretched: a blanket, a tarp, or several jackets closed and threaded onto each other. An emptied backpack frame can also serve as a one-off reinforcement to stiffen the whole thing, and climbing rope or webbing woven back and forth between the two poles creates a serviceable net when nothing else is available to cover the frame.
Material choice mostly depends on what’s actually on hand: no need to chase the perfect solution when a simple, sturdy combination is plenty to cover the necessary distance. On a ski tour or a canoe trip, the skis themselves or a double-bladed paddle can stand in for natural poles when no suitable branch is anywhere nearby.
Two things matter more than anything else when picking material: rigidity (a pole that bends under an adult’s weight won’t hold up over several hundred meters) and total length, which needs to clear the injured person’s height by a good margin so carriers have room to grip on both sides.
Two sturdy poles, the base of any improvised stretcher
Each pole needs to extend at least 30 cm past the person lying down on each side, giving carriers a solid grip without risking a slip mid-transport. Testing each pole’s strength by pressing down firmly before finalizing the stretcher prevents it from giving way mid-evacuation, a particularly high risk with dead wood picked up off the ground.
Telescopic trekking poles, fully extended and locked, work just as well as natural branches, with the advantage of already-known and tested strength before the trip even started. Checking the lock with both hands, pulling hard in both directions, avoids the bad surprise of a pole collapsing under weight mid-evacuation.
A live branch, still green and flexible, bends without necessarily snapping under load, which actually makes it more dangerous than a dry dead branch: it gives the illusion of holding while slowly sagging. Going with dead wood that’s still firm to the touch, with no spongy patches or signs of rot, gives a far better result.

Jackets or tarp, how to close up the stretcher
For the jacket method, fully closing each jacket (zip or buttons), lining them up overlapping each other, then sliding both poles through the sleeves turned inward creates a continuous carrying surface. A tarp or tent fly, wrapped tightly around each pole and secured with rope or paracord, offers a faster solution when that gear is on hand, and it tends to hold up better over a long carry than a chain of jackets whose zips can pop under repeated strain.
Checking that the carrying surface stays taut with no deep folds avoids uncomfortable pressure points for the person being carried, sometimes over a long distance. Layering two or three jackets instead of a single layer spreads the weight better and cuts the odds of a zip or a button giving out partway through.
A sleeping bag split open along its full length and laid flat also works well as a carrying surface, with the added bonus of insulating the person being carried from the cold rising up from below, a detail that matters enormously over a trip lasting several hours.
Suspected spinal injury, what changes everything
The moment a significant fall, a head impact, or pain in the neck or back suggests a possible spinal injury, the absolute priority becomes immobilizing the head before moving any other part of the body. One person dedicated solely to stabilizing the head with their hands, while others handle the rest, is the best option when the group has enough people.
Without anyone free for that task, wedging the head between two rolled-up jackets or two bags on either side limits side-to-side movement during transport, without fully replacing genuine manual immobilization. Asking the injured person whether they feel tingling, numbness, or weakness in their arms or legs gives a valuable read on how serious the injury might be, worth repeating at intervals throughout the trip.
The urge to sit someone up or straighten them out right after a fall, just to “check if they’re okay,” ranks among the moves to avoid whenever a spinal injury is possible: that motion can turn an injury that would have stayed stable, once immobilized, into something worse.
Carrying with several people without worsening the injury
Carrying an improvised stretcher ideally takes four people, one at each corner, standing and moving together on a clear verbal signal. A poorly coordinated movement, where one pole lifts before the other, jolts the whole stretcher and transmits that motion directly to the injured person.
Moving at a slow, steady pace, calling out each obstacle in the terrain before crossing it, greatly reduces the jolts that worsen an existing injury the most. Assigning a single person to call the instructions (“moving”, “stopping”, “lifting on three”) avoids the confusion that quickly sets in when four carriers each try to direct the movement. Ideally that caller walks near the patient’s head, close enough to watch for any change in their condition while still keeping an eye on the group’s footing.
Rotating carriers every ten to fifteen minutes on a long carry keeps the pace steady, since fatigue is exactly what causes the missteps and mistimed movements that show up toward the end of a long haul. Swapping positions during a brief, controlled stop, rather than mid-stride, avoids the exact kind of jolt this whole rotation is meant to prevent.
Securing the patient before hitting the trail
Strapping the person to the stretcher with straps, rope, or even spare shoelaces, across the chest and thighs, keeps them from sliding or tipping on sloped or uneven ground. This precaution matters twice as much for someone semi-conscious, unable to catch themselves if the carriers lose their balance.
Keep the straps snug rather than cinched down hard: a strap pulled too tight across the chest restricts breathing, which becomes a serious problem for someone already weakened. Insulating the injured person from the ground and wind, with a space blanket or any spare clothing on top of the carrying surface, prevents the hypothermia that sets in fast on someone lying still, even in moderate temperatures. Checking their level of consciousness at regular intervals throughout the trip also catches a decline before it turns critical.
When not to move an injured person at all
Immediate danger (fire, rockfall, rising water) justifies moving someone even with a suspected serious injury, for lack of a safer alternative. Outside of immediate danger, waiting for help on the spot, while signaling the exact position, is often preferable to an improvised evacuation that risks worsening an unconfirmed spinal injury. That call takes some nerve, especially facing someone who insists on walking despite the pain: reassuring them and helping them wait it out is sometimes the most useful thing you can do.
Insulating the person from the ground and covering them while waiting for help still matters even in this case: staying completely still cools the body down far faster than even a slow walk would.
What turns an improvised evacuation into a bigger risk
Rushing the transport to “get it over with,” rather than taking time to build a genuinely stable stretcher, is the most common mistake under stress. Using poles that are too short or poorly tested, which give way mid-route, turns an already delicate evacuation into a fresh accident. Pushing onto technical terrain (a scree field, a steep slope, a narrow passage) without first scouting a more workable alternate route often costs more time than the detour itself would have taken. Having already thought through this kind of scenario before leaving, on the same checklist as the rest of the 72-hour survival kit, changes a lot about how fast you react the day it actually happens.
The right gear gets an evacuation ready before it happens
A well-stocked first aid kit is the first step before even thinking about an improvised stretcher: our first aid kit guide covers what to keep within reach. Once the evacuation starts, signaling your exact position matters just as much as the transport itself: our survival SOS beacon comparison covers the models that keep that reference reliable even far from any network.
What I’d recommend to anyone who regularly heads out in a group: practice building an improvised stretcher once, even briefly, before actually needing it. The day it happens, nobody has the time or the composure to improvise a technique they’ve never practiced, and the ten minutes spent training beforehand pay for themselves many times over that day.
