Hydration 101: Your Guide to Water While Hiking

Written by Korrin Bishop

Water is one of the unsung heroes of backpacking and hiking trips. Humans can only survive about three days without water, and our need for it increases with our activity level, as we lose fluids through sweat. But it can be hard sometimes to gauge just how much we need. If you’re newer to backcountry travel, you might also have questions around where to source your water or the best way to carry it.

Well, never fear! Our Hydration 101 blog is here to help answer all of your questions about water on the trail, including:

  • How much water should you drink while hiking?
  • What is the best way to carry your water while hiking?
  • What water is safe to drink in the backcountry?
  • What are the signs of dehydration?

Let’s dive in!
