Packing Checklist - 7 Tips for the Hike

  • First of all, waterproof hiking boots; hiking with wet feed ensures a cold afterwards.
  • Hiking pools are essential IMO for the steep ascent and descent.
  • Headlight; I always carry one in my backpack if I can't get back in time. Days are long in the summer, up to 16 hours, but you never know.
  • Everything for the strong sun; sunscreen, hat, sunglasses.
  • Rain- and windproof jacket and warm layers; weather can change quickly. I always carry a lightweight, packable down jacket. 
  • Energy food, lunch, nuts, fruits for the long day of hiking
  • Plenty of water and most important electrolytes; you will sweat more than expected.
