The Overdue Hiker Plan: what your family should do if you do not return

If you are injured, lost, or stranded and cannot call for help, the clock does not start until someone notices you are missing and reports it. That gap can be hours or days, and it is often the difference between a straightforward rescue in daylight and a prolonged search in worsening conditions. An overdue-hiker plan closes the gap. It guarantees that a specific person is expecting you back at a specific time, knows precisely where you went, and knows exactly what to do the moment you are overdue. It is free, it takes ten minutes, and it works even when your phone is dead, your satellite device has failed, or you are unable to reach either. This is the backstop behind every other piece of safety gear.

In the United States, the simplest reliable action is to call 911 and report an overdue hiker. The dispatcher will route the call to whichever agency is responsible for search and rescue in that area. On most public land that is the county sheriff, who coordinates SAR; inside a national park it is the National Park Service; and land-management agencies such as the Forest Service or Bureau of Land Management may be involved depending on where you are. If you know the specific local sheriff or park dispatch number for your trip, put it on the plan as well, but 911 is the dependable default. Outside the United States, the responsible agency and emergency number differ by country, so confirm the correct contact for the areas you travel and write it on the plan.

The timing is just as important as the number. Your contact should act at the raise-the-alarm time you agreed, not before and not long after. Reporting too early, at the first sign of a slightly late return, risks a false alarm from a slow descent or a flat tire, which is why the buffer exists. But waiting too long is the far more common and more dangerous error: every hour lost after the cutoff is an hour of lost daylight and a wider area to search. When the cutoff passes with no contact, your person should make the call. Search and rescue would far rather stand down a false alarm than start a search half a day late.

When your contact calls, responders will ask for the information that lets them plan a search: your planned route and trailhead, your last known location and expected campsites, the make, model, color, and license plate of your vehicle and where it is parked, a physical description including the colors of your clothing and pack, how many people are in your party, your experience level, any medical conditions or medications, and what communication device you carry and its number. This is exactly the information in the printable plan above, which is the point of filling it in: instead of your family trying to recall details under stress, they can read the whole picture straight off the page. Bright clothing and gear colors, noted on the plan, help searchers spot you from a distance or from the air.
