When you hit the trail, it’s important to stay hydrated. But how much water should you bring with you? The answer depends on a number of factors, including the length of your hike, the weather, and your physical activity level.

Here’s a guide to help you figure out how much water to bring on your next hike.

Water Needs for Hiking

The average person needs about 64 ounces, or eight cups, of water per day. However, when you’re hiking, you’ll need more than that.

A good rule of thumb is to bring along one gallon of water per person, per day. If you’re hiking in hot weather or at a high altitude, you may need even more than that.

Another factor to consider is your physical activity level. If you’ll be hiking at a steady pace for several hours, you’ll need more water than if you’re taking frequent breaks. And if you tend to sweat a lot or are carrying a heavy pack, you may also need more water than average.

Ways to Carry Water on a Hike

Once you’ve determined how much water you’ll need for your hike, it’s time to think about how you’re going to carry it.

If you’re only going for a short day hike, you might be able to get away with carrying a single water bottle.

But for longer hikes, you’ll need something more substantial, like a hydration bladder or CamelBak. These devices allow you to carry large amounts of water without weighing yourself down too much.


Staying hydrated is essential when hiking—but how much water should you bring? It depends on the length of your hike, the weather conditions, and your physical activity level. In general, it’s a good idea to carry one gallon of water per person, per day.

And don’t forget to pack a way to carry all that water! A hydration bladder or CamelBak is perfect for long hikes.
