A Special Message about Backcountry Safety

Travel in Grand Teton's backcountry has inherent risks; hikers assume complete responsibility for their own safety. Rescue is not a certainty. Your safety depends on your own good judgment, adequate preparation, and constant attention. Backcountry users should be in good physical condition and should be prepared to survive on their own. Appropriate equipment and the knowledge of how to use it are essential for a safe trip. Your safety is your responsibility. Watch our video podcast about backcountry trip planning.

If You Get Lost

  • Stay calm and stay put . . . you will be found sooner.
  • Stay in a clearing or on a large outcrop where you will be most visible.
  • Attract searchers by making noise and signaling with colorful clothing or a mirror.
  • If someone is injured, provide whatever treatment you can.
  • If possible, do not leave the injured party alone.
  • Send for help with the exact location marked on a map, description of injuries, list of equipment, and treatment given.
