How to do it

  1. Check the forecast and the trail conditions the night before.
  2. Pack about half a liter of water per hour of hiking, more in heat.
  3. Pack snacks for the hike plus some extra in case you are out longer.
  4. Add a warm layer and a rain shell, even on a sunny morning.
  5. Add a headlamp, a paper map of the area, a whistle, a small first aid kit, sunscreen and a hat.
  6. Charge your phone and download an offline map, and bring a small power bank.
  7. Text someone your route, where you are parking and when to raise the alarm.
  8. Set a turnaround time before you start and keep to it.

Stop and call a professional if

  • Someone is injured and cannot walk out, is confused from cold or heat, or you are lost and it is getting dark: call your local emergency number, 911 in the US, and stay where you are.

Common mistakes

  • Relying on the phone as the only map and light.
  • Starting late with no plan for getting back before dark.
  • Heading out without telling anyone the route.

Quick self-check

Three questions. Your last score is kept in this browser.

1. Why carry a headlamp on a morning hike?
2. Who should know your route?
3. What is a turnaround time for?
