I have become separated from my group outdoors

One person stops for a moment, the others walk on – and suddenly nobody is within sight or calling distance. What happens now decides whether you find each other quickly.

First

  1. Stop and calm down (STOP). Do not search back and forth.
  2. Call out and give three blasts on a whistle, then listen.
  3. Try to reach the others by phone or message; share your location.
  4. If injured, in danger or facing darkness without equipment: call the local emergency number (112 in the EU).

Call emergency services if

  • A child or an injured, ill or weak person is missing
  • Darkness or bad weather is setting in
  • Dangerous terrain or water nearby
  • The person cannot be found after a short search

What is happening

One person stops to take a photo, another walks ahead, at a junction two parts of the group take different directions – and suddenly nobody is within sight or calling distance. In a forest, in fog, in wind or beside a roaring stream this can happen within minutes, often without anyone noticing straight away.

The first reaction is usually hectic searching. Both sides set off to find the others – and often move further apart in doing so. Anyone on their own is also tempted to cut across country to catch up with the group, and loses the trail as well.

It becomes risky if the separated person is a child, injured, ill or poorly equipped, if it is getting dark, the weather turns or there is water or drop-offs nearby. Then time matters, and an early emergency call is not an overreaction – rescuers would rather start looking early for someone who soon turns up than too late.

What helps most is agreed beforehand: whoever loses the others stays put; the group waits at junctions; everyone has a whistle; there are meeting points. For the group: stay together, search methodically from the point last seen and get help early.

Step by step

  1. Phase 1

    If you are on your own: immediately

    • Stop and calm down – do not search back and forth.
    • Shout and give three whistle blasts, then listen; repeat at intervals.
    • Call or message the others and share your location.
    • If there is an agreed meeting point you can reach safely, go there – otherwise stay where you are.

  2. Phase 2

    If someone from the group is missing: immediately

    • Keep the group together and count heads.
    • Note down: where and when was the person last seen? Clothing, equipment, state of health, phone?
    • Call and message the person.
    • One person stays at the point last seen or the meeting point.
    • Only search in pairs, with a fixed time limit and an agreed return point; call, whistle and listen as you go.

  3. Phase 3

    If it takes longer

    • Call the local emergency number (112 in the EU) as soon as a child or a vulnerable person is missing, darkness falls, the weather turns, there are hazards nearby or a short search has failed.
    • Give the dispatcher all the details you have gathered and follow their instructions; after that the group no longer searches widely on its own.
    • On your own: stay at a clearly visible, safe spot, show bright clothing, keep warm and save your battery.
    • In darkness, do not keep searching in unknown terrain; set up a sheltered spot and use light to draw attention.

  4. Phase 4

    When you find each other

    • Inform the dispatcher and everyone involved at once so that no search continues.
    • Count heads again and check that everyone is all right.
    • Talk together about how it happened and set rules for the rest of the trip.

What to watch out for

  • Two searchers drift apart

    If both sides search at the same time, they easily miss each other. One side stays put – usually the person who is alone.

  • Sounds get swallowed

    Wind, rushing water and dense forest strongly muffle shouts. A whistle usually carries further than your voice and takes less effort.

  • Children do not always answer

    Children are sometimes afraid of getting into trouble or of unfamiliar voices and do not answer. Search hiding places nearby too.

  • Battery

    Repeated calls, navigation and torch use drain the phone quickly. Agree when you will check in and save power in between.

  • Water and drop-offs

    If a child is missing near water or drop-offs, call the emergency number at once and have those places searched first.

Common mistakes

  • Everyone fans out on their own to search.
  • Delaying the emergency call because you do not want to be a nuisance.
  • Following the group's assumed direction cross-country.
  • Agreeing no rules and no meeting points beforehand.
  • Not cancelling the search once you have found each other.

Prepare in advance

  • Agree rules before the trip: whoever loses the others stays put; the group waits at every junction; one person walks at the back.
  • Give everyone a whistle and explain the signals.
  • Exchange phone numbers and set up location sharing beforehand.
  • Take a photo of the group in the morning – in an emergency it shows the dispatcher clothing and appearance.
  • With two-way radios, agree a channel and fixed check-in times.

Special consideration

Children
Teach children to stay put if they get lost, for example by a tree, to answer when called and to blow their whistle. Tell them nobody will be cross and rescuers are helpers. Bright clothing makes them easier to see.
People with dementia or orientation problems
They may not respond to calls and can walk a long way without seeking help. If they are missing, call the emergency number at once.
Dogs
A runaway dog is no reason for the group to split up. People come first.

Basics for this situation

Why: Always applies to this situation – regardless of your answers.

All rules of this situation (6)

  1. [not active] If Who is missing? = I am on my own

    Without a clear plan it is usually better to stay at a clearly visible spot than to keep walking. Go to the last agreed meeting point if you can reach it safely.

  2. [not active] If Who is missing? = Someone from our group is missing

    Keep the group together; do not let everyone search alone. Return to where the person was last seen. If they are not found soon, call the emergency number early.

  3. [not active] If Time of day = Dusk / night

    In darkness do not keep searching in unknown terrain; find a sheltered spot and make yourself visible with light.

  4. [not active] If Communication = Phone with signal

    Send your coordinates, save battery and stay reachable.

  5. [not active] If Communication = No signal

    Rely on sound and visual signals. An emergency call may still go through on another network – try it.

  6. [not active] If Communication = Two-way radios in the group

    Use the agreed channel and call at regular intervals.
