Water: Your Lifeline in an Adventure


From a casual day hike to a multi-day trek, water is a hiker's most precious cargo.  Dehydration can set in quickly, compromising your energy levels, decision-making skills, and overall safety. Knowing how to find water, safely replenish your supply, and prevent running out is key for a successful and enjoyable adventure.



Plan Ahead: How Much Water Do I Need?

  • The Basics: Start with the general guideline of one liter of water per two hours of hiking in moderate conditions.

  • Adjusting Factors: Increase your water intake for:

  • Hot weather and exertion

  • High altitude

  • Medical conditions or medications that influence hydration

  • Don't Wait for Thirst: Drink small amounts frequently, as thirst is a sign of dehydration already setting in.



Scenario: Jess's Mt. Apo Hike

Jess, an avid hiker, set out to conquer Mt. Apo, the Philippines' highest peak. Despite packing what she thought was enough water, an unexpected detour and scorching heat left her parched with miles left to the next campsite. With the sun starting to set, she spotted a stream - a potential water source, but was it safe?


Water Sources on the Trail

When planning your hike, prioritize reliable water sources like park fountains or designated watering points. Springs clearly marked as safe on well-respected trail maps can also be a good option. However, it's crucial to treat streams, rivers, and lakes as potentially contaminated.  Always filter or purify water from these natural sources before drinking to avoid waterborne illnesses.  Do some research beforehand – your hike's terrain may have seasonal water sources worth marking on your map. Knowing about these "hidden gems" can be incredibly valuable for water management on longer adventures.


Filtration and Purification: Your Shield Against Waterborne Illness

Even on hikes with "reliable" water sources, having a backup purification method is wise.

  • Your Options:

  • LifeStraw: Ultralight for drinking directly from streams

  • Gravity Filters: For larger amounts of water, perfect for camps

  • Purification Tablets: Effective but can affect water taste

  • Boiling: Time-consuming but reliable in a true pinch

  • Choose What Fits: Consider your trip length, group size, and personal preference.



Preventing the Dreaded "Ran Out of Water" Scenario

  • Map Study: Scrutinize your map for potential water sources, noting distances between them.

  • Carry More Than You Think: Better to have extra than to be desperately thirsty.

  • Smart Storage: Use a mix of bottles and a hydration bladder for easy access while hiking.

  • Refill at Every Opportunity: Even if it's just a few sips, top up at reliable water sources whenever possible.


Water shouldn't be an afterthought on the trail. By planning your water needs, knowing where to find potential sources, and carrying the right purification tools, you'll be empowered to stay hydrated and safe on any hike. Remember, water isn't just about survival - it supports peak performance and enjoyment on your adventures.


Additional Tips

  • Electrolytes: On particularly strenuous hikes, consider electrolyte tablets or powders to replenish essential minerals lost through sweat.

  • Flavor Boost: If you dislike the taste of purified water, flavor additives can make hydration more palatable.
