Stay Hydrated on the Trail
Water is one of the most important things to bring on any hike. Staying properly hydrated helps you stay focused, avoid fatigue, and regulate your body temperature — especially in hot, dry, or high-altitude conditions.
This page explains how much water you need, how to carry it, and what to consider when refilling on the trail.
How Much Water Should You Bring?
A general guideline is to carry about half a liter (16–17 ounces) of water per hour of moderate hiking in mild conditions. Increase your intake in hot weather, on uphill climbs, or if you’re carrying a heavy pack.
Factors that affect water needs:
- Temperature and humidity
- Trail length and difficulty
- Body weight and sweat rate
- Altitude and sun exposure
- Personal hydration habits
Always err on the side of carrying extra water, especially if water sources are uncertain.

Treating Water on the Trail
If you’re hiking longer distances or in remote areas, you may need to refill from streams or lakes. Even clean-looking water can contain bacteria or parasites, so it’s important to treat it.
Common Water Treatment Methods:
- Water Filters: Lightweight, reusable, and fast. Great for removing bacteria and protozoa.
- Purification Tablets: Small and packable. Takes 30 minutes or more and may affect taste.
- UV Purifiers: Use light to kill pathogens. Require batteries and clear water.
- Boiling: Effective but time-consuming and requires a stove.

Hydration Tips for Hikers
- Start your hike well hydrated — drink water before you hit the trail
- Sip small amounts often rather than gulping large amounts all at once
- Monitor the color of your urine — pale yellow means you’re on track
- In cold weather, don’t forget to drink — dehydration is still a risk
- In hot weather, pair water with electrolytes to prevent imbalances
