It’s always important to stay hydrated, but when you’re out hiking it’s even more crucial. You might not feel thirsty, but that doesn’t mean you’re not losing water. In fact, you can lose up to a quart of water per hour when hiking in warm weather.

How Much Water Should You Bring on a Day Hike

The answer to this question depends on a few different factors, including the temperature, the intensity of the hike, the altitude, and your own individual physiology.

Generally speaking, you should plan on bringing 1 liter of water for every 2 hours you’ll be hiking. So, if you’re planning a 4-hour hike, you should bring 2 liters of water. If you’re hiking in hot weather or at a high altitude, you might need even more than that.

It’s easy enough to empty out your backpack at the end of the hike if you don’t drink all of it, but if you run out of water partway through your hike it could be very dangerous.

In addition to bringing plenty of water with you, it’s also a good idea to know where nearby sources of water are in case of emergencies, especially if you’re hiking mount Everest for example.

Conclusion

Staying hydrated is key to having a safe and enjoyable day hike. Make sure to bring 1 liter of water for every 2 hours you’ll be hiking, and consider bringing more if the weather is hot or if you’ll be hiking at high altitudes.

Knowing where to find sources of water along your route is also important in case of emergencies.
