The 11 Essentials for Hiking

  • Food and Water: Carry high-energy snacks and plenty of water. Giardia is a threat so always treat water by boiling or using an appropriate filter.

  • Clothing: Weather can change dramatically in the mountains. Carry rain gear and warm clothing including wool socks, gloves and hat.
  • Navigation: Carry and know how to use a topographic map and compass.
  • Light: Flashlight with spare batteries and bulb.
  • Fire: Waterproof matches and fire starter such as a candle.
  • Sun Protection: Sunglasses and sunscreen.
  • First Aid: Make sure to include any special medications. For a list of supplies visit the first aid page.
  • Knife: Folding pocket knife.
  • Signal: Carry both an audible and visual signal, such as a whistle and a metal mirror.
  • Emergency Shelter: Plastic tube shelter or waterproof bivouac sack or emergency blanket.
  • The Eleventh Essential: This is your call. Think about what might be important to you, but everyone should try to take along a lot of common sense.
