What to do when you realize you’re lost

The first five minutes: STOP

When a trail, landmark, or expected turn no longer matches your plan, resist the urge to walk faster. The U.S. Forest Service teaches the mnemonic STOP: Stop, Think, Observe, Plan. It creates a pause before uncertainty turns into distance.

1. Stop. Stay put long enough to slow your breathing, check for immediate hazards, and prevent the group from separating.
2. Think. Recall the last place you were certain of your location. Note the time, direction of travel, and any recent junction, creek, road, or landmark.
3. Observe. Check your map, compass, GPS, downloaded map, elevation, terrain, weather, daylight, water, clothing, injuries, and phone battery.
4. Plan. Choose one deliberate action. Write it down or say it aloud so the group shares the same plan.

Should you stay or move?

There is no single rule for every landscape, but staying near your last known route or location often makes you easier to find. The National Park Service advises lost hikers to stay put if they cannot safely return to a known location. Wandering expands the search area and spends daylight, water, and energy.

Movement may be necessary when your current position has an immediate hazard such as wildfire, rising water, rockfall, or severe exposure. Move only far enough to reach a safer nearby position, and leave a clear indication of your direction if doing so is safe and permitted.

Make yourself findable

• Call or text 911 when rescue is needed. A text may transmit in marginal service when a call does not.
• Share coordinates from your phone or GPS, plus nearby terrain and your clothing colors.
• Preserve battery: lower screen brightness, close unnecessary apps, and keep the device warm in cold conditions.
• Use a whistle in sets of three, then pause and listen. Do not shout continuously.
• Place bright gear where it can be seen from the air without creating a new hazard.

If you left a trip plan with a trusted contact, rescuers have a useful starting point. That simple step matters more than posting a live update nobody is assigned to monitor.

Prepare for weather or darkness

Before you are cold, wet, or out of light, put on insulating layers, choose a protected position away from dead trees and flood channels, and make your emergency shelter ready. Keep the essentials you may need after dark on your body. Drink and eat deliberately; panic and hard travel can waste both.

Fire may help in some settings, but restrictions, wind, fuel conditions, and wildfire risk can make it dangerous or illegal. Check local rules and use another heat or visibility method when fire is not clearly safe.
