How Many Liters Is a 3 Day Backpacking Trip?

By Michael Ferguson

Backpacking is an incredibly rewarding experience and an excellent way to explore the outdoors. But when planning a backpacking trip, one of the most important considerations is how much water to bring. Knowing how many liters is a 3 day backpacking trip can help you ensure that you have enough hydration for your journey.

When it comes to packing for a backpacking trip, it’s important to consider the weather and terrain. If you’re hiking in hot, dry conditions, you’ll need more water than if you’re in a cooler climate or in areas with rivers and streams.

Additionally, if you’re carrying a heavy backpack full of gear, you’ll need more water to stay hydrated. It’s also important to consider what other activities you’ll be engaging in during your trip. If you plan on swimming or rock climbing, for example, having extra water can be beneficial.

In general, experts recommend bringing at least 1 liter of water per person per day for a 3-day backpacking trip. This amount should provide enough hydration while allowing room in your backpack for other items like food and clothing. If the conditions are particularly hot or dry, however, it’s best to increase this amount so that each person has at least 2 liters per day.

It’s also important to remember that drinking water isn’t the only way to stay hydrated during a backpacking trip. Eating foods like fruits and vegetables that are high in water content can help boost your overall hydration levels and reduce the amount of drinking water needed. Additionally, if possible it’s always best to take advantage of natural sources of clean drinking water such as rivers and streams.


A 3-day backpacking trip should include at least 1 liter of drinking water per person per day but depending on the climate and activities planned during the journey this amount may need to be increased up to 2 liters per person per day. Additionally, eating high-water content foods can help reduce the overall amount of drinking water needed on the trip.
