How Much Water For Camping? [Per Person Per Day]

I bring lots of water on camping trips.

I’ve learned the hard way that not bringing enough water can quickly turn a fun trip into a miserable one.

Key Takeaways

  • You should aim to drink one gallon (4 liters) of water per day in hot weather, ½ gallon (2 liters) per day in moderate weather
  • Knowing how to find and purify water sources in the wilderness, as well as how to pack and store water, can help ensure you have a sufficient supply of water for your trip.

Importance of Water for Camping

As an experienced camper, I know how crucial it is to stay hydrated while camping. Water is essential for our bodies to function properly, and we need to consume enough of it to stay healthy. However, water is not only important for drinking; it is also necessary for cooking and cleaning.


Climate and Weather Conditions

Climate and weather conditions also play a crucial role in determining the amount of water needed. Hot and dry weather conditions increase the risk of dehydration, and more water will be needed to stay hydrated. In contrast, cold weather conditions may decrease the need for water, but it is still essential to drink enough fluids to avoid dehydration.

I meticulously planned a camping trip to the serene wilderness of the Adirondack Mountains.

As an avid outdoor enthusiast, I knew hydration was key, so I made sure to pack plenty of water. For this particular adventure, I decided to bring along a new piece of gear—a high-capacity, rugged water container that could hold up to 7 gallons of water, ensuring that my group and I would have enough to last the entire weekend.

The container was a behemoth, made of a durable, BPA-free blue plastic that could withstand the bumps and scrapes of backcountry travel. It measured about 23 inches in height and 15 inches in diameter, a sizable footprint that was a testament to its ability to quench the thirst of several campers. It boasted a spigot at the bottom for easy dispensing, which I was looking forward to using at our base camp.

Packing the car was a challenge in itself, with the water container taking up a significant portion of the trunk space. I had to play a strategic game of Tetris with our gear, carefully placing tents, sleeping bags, and cooking equipment around the blue cylinder that was the lifeblood of our trip. The drive to the mountains was filled with anticipation, as I imagined the cool, refreshing water being the perfect complement to the smoky flavor of campfire-cooked meals.

Upon arrival, I hefted the container out of the trunk, its weight a solid reminder of its precious cargo. We trekked to our campsite, a secluded spot by a crystal-clear lake, with the container secured in a small, two-wheeled cart I’d brought along just for this purpose. The terrain was uneven, with roots and rocks threatening to overturn our precious supply, but I navigated the path with the care of a ship’s captain steering through stormy seas.

Setting up camp was a breeze, and the water container took pride of place near the fire pit, its blue body glinting in the dappled sunlight that filtered through the canopy of leaves above. As the days unfolded, that water container became more than just a vessel; it was a gathering point where we’d fill our bottles before setting out on hikes, wash our hands before meals, and share stories of our day’s adventures as we sipped and refreshed ourselves.

The first gulp was heavenly. It tasted pure and sweet, with a freshness that only seemed to enhance the natural beauty surrounding us. That evening, as we sat around the campfire, the container beside us like an old friend, I couldn’t help but feel a sense of pride. I had brought sustenance and comfort to my fellow campers, and it felt good.

On the last day of our trip, I noticed the water level had significantly dropped, but we still had enough to see us through. It was a testament to my planning and the container’s generous size. As we packed up, I made sure to pour the remaining water over our extinguished campfire, ensuring every ember was cold. The container, now much lighter, seemed to echo with the laughter and conversations it had presided over.

Back home, I cleaned and stored the container, ready for our next adventure. It had become more than just an item on my camping checklist; it was a symbol of the care and preparation that went into each trip. It held not just water, but memories of shared experiences and the promise of many more to come.

Hydration and Health

When camping, we need to drink enough water to stay hydrated. The amount of water we need varies depending on several factors, including age, gender, activity level, and climate. As a general rule, we should aim to drink one gallon (4 liters) of water per day in hot weather, ½ gallon (2 liters) per day in moderate weather, and ¼ gallon (1 liter) per day in cold weather. These are just guidelines, and we should adjust our water intake depending on the activities we plan on doing and the climate we are in.

Cooking Requirements

Water is also essential for cooking while camping. We need water to rehydrate food, cook pasta and rice, and prepare hot drinks like tea and coffee. When planning a camping trip, we should consider how much water we will need for cooking and bring enough with us.

Cleaning Needs

Lastly, water is necessary for cleaning while camping. We need water to wash our dishes, clean our cooking utensils, and even wash ourselves. When camping, we should be mindful of our water usage and try to conserve as much as possible. We can do this by using biodegradable soap and washing dishes in a basin instead of running water.

Determining the Amount of Water Needed

When planning a camping trip, it is essential to determine the amount of water needed to avoid dehydration and ensure a safe and enjoyable experience. The amount of water needed depends on various factors, including the duration of the trip, intensity of activities, and climate and weather conditions.

Duration of the Trip

The duration of the camping trip is an essential factor in determining the amount of water needed. As a general rule, an adult requires at least one gallon of water per day. Therefore, a weekend camping trip would require at least two gallons of water per person, while a week-long trip would require at least seven gallons of water per person.

Intensity of Activities

The intensity of activities also affects the amount of water needed. If the camping trip involves strenuous activities such as hiking, biking, or kayaking, the body will lose more water through sweating, and more water will be needed to replenish the lost fluids. In this case, it is recommended to bring extra water or a water filtration system to ensure an adequate supply of clean drinking water.

Water Sources in the Wilderness

When camping, it’s important to know where you can find water sources in the wilderness. In general, there are two types of water sources: natural and man-made.

Natural Sources

Natural sources of water include springs, streams, rivers, and lakes. These sources are typically safe to drink from, but it’s still important to filter or purify the water to remove any potential contaminants.

When collecting water from natural sources, it’s best to choose a spot upstream from where people or animals may have contaminated the water. Avoid collecting water from stagnant sources, as they may contain harmful bacteria.

Man-Made Sources

Man-made sources of water include wells, pumps, and water stations. These sources are generally safe to drink from, but it’s still important to check the water quality before consuming.

When using man-made sources of water, be sure to follow any posted instructions for use and disposal. In some cases, you may need to bring your own container to collect water.


Water Purification Methods

When camping, it’s important to have access to clean drinking water. Even if the water source appears to be clean, it may still contain harmful bacteria and parasites. Here are some common water purification methods to consider:


Boiling is one of the most effective ways to purify water. Bring the water to a rolling boil for at least one minute, or three minutes if you’re above 6,500 feet. This will kill most bacteria and parasites. However, boiling won’t remove any chemicals or sediment that may be present in the water.

Water Filters

Water filters are a popular way to purify water while camping. They work by physically straining out bacteria and parasites. Look for a filter that’s designed to remove the specific contaminants that are common in the area where you’ll be camping. Keep in mind that water filters can clog over time, so be sure to follow the manufacturer’s instructions for cleaning and replacing the filter.

Chemical Purification

Chemical purification is another option for purifying water while camping. Chlorine or iodine tablets are commonly used for this purpose. These chemicals kill bacteria and parasites, but they can leave an unpleasant taste in the water. Be sure to follow the manufacturer’s instructions carefully to ensure that you’re using the correct amount of chemical for the amount of water you’re treating.


Packing and Storing Water

When planning a camping trip, it is crucial to ensure that you have enough water to last for the duration of your stay. Here are some tips to help you pack and store water for your camping trip:

Water Containers

Choose containers that are sturdy and can hold up to the rigors of camping. Avoid using plastic bags or thin bottles that can easily puncture or leak. Here are some good options:

  • Water jugs: These are great for car camping as they can hold up to 5 gallons of water.
  • Collapsible water containers: These are perfect for backpacking as they take up less space when empty.
  • Water bladders: These are ideal for backpacking as they can be easily attached to your backpack.

Water Preservation

Water preservation is essential when camping. Here are some tips to help you preserve your water:

  • Keep water in a cool, dark place: This will help prevent the growth of bacteria and algae.
  • Use a water filter: A water filter can help remove any impurities or contaminants in your water.
  • Bring water purification tablets: These can be used to purify water from natural sources such as streams and lakes.

By following these tips, you can ensure that you have enough water for your camping trip and that it stays fresh and clean throughout your stay.

Emergency Water Solutions

When camping, it is important to have a plan for emergency water solutions. In case of an emergency, you should have access to clean water to avoid dehydration. Here are some techniques for collecting water and signs to look for when searching for water sources.

Water Collection Techniques

There are various techniques for collecting water while camping. Here are some of the most common methods:

  • Rainwater collection: Collecting rainwater is one of the easiest ways to get clean water. You can use a tarp or a rainfly to collect rainwater by placing a container underneath.
  • Water filtration: Water filtration is another effective way to get clean water. You can use a portable water filter or a water purification system to filter water from a natural source such as a river or lake.
  • Water condensation: You can also collect water by condensation. You can use a clear plastic bag to collect water from plants. Tie the bag around a branch and wait for the water to condense.

Signs of Water Nearby

When searching for water sources, it is important to look for signs of water nearby. Here are some signs to look for:

  • Wildlife: Animals such as birds and insects are attracted to water sources. If you see wildlife in an area, it may be a sign that there is water nearby.
  • Vegetation: Plants such as cattails and willows grow near water sources. If you see these plants, it may be a sign that there is water nearby.
  • Topography: Water flows downhill, so if you are in a valley or near a depression, there may be water nearby. Look for areas where the ground is damp or where there are natural depressions.

By using these techniques and looking for signs of water nearby, you can ensure that you have access to clean water in case of an emergency while camping.

  • Water sources: Campgrounds may have different water sources, such as wells, taps connected to municipal water systems, or natural sources like rivers, lakes, or streams. Check with the campground management or online resources to confirm water availability before your trip.
  • Drinking water: Some campgrounds provide potable (safe for drinking) water through designated taps or spigots. Make sure to use only water from sources clearly marked as safe for drinking.
  • Non-potable water: If the campground provides non-potable water, it is not safe for drinking but can be used for cleaning, washing dishes, or putting out campfires. Remember to treat this water before consuming it.
  • No water available: In more remote or primitive campgrounds, there might not be any water sources available. In these cases, you’ll need to bring your water supply or locate and treat water from nearby natural sources.
  • Water treatment: If you plan to use water from natural sources, such as rivers, lakes, or streams, make sure to treat it before drinking or cooking with it. You can use boiling, chemical treatment (water purification tablets or drops), or water filters to remove potential contaminants.
  • Water storage: Bring appropriate containers for storing water during your trip. BPA-free containers designed for outdoor use are recommended. Make sure they are clean before filling them and keep them sealed when not in use to prevent contamination.



Q: What if I’m hiking while camping? Do I need more water? A: Yes! Hiking can be thirsty work, especially when you’re carrying that mystery can of beans no one wants to eat. Factor in an additional half to one liter of water per hour of hiking. The same goes for any other strenuous activities, like bear wrestling or attempting to set up an IKEA tent without instructions. I bring 1gal per day per person in a place that has a water tap. I double that if in the wild.

Q: Can’t I just drink from streams or lakes? A: If you’re fond of waterborne illnesses, sure. Otherwise, you might want to treat any water you find in the wild before drinking it. There are lots of options for this, from filters and purifiers to boiling or using chemical treatments. Remember, that clear mountain stream may be photogenic, but it could also be hosting a family reunion of harmful bacteria and parasites. I have accidentally gulped some lake water swimming and did not get sick but I do not recommend it.


Q: Should I ration my water if I’m running out? A: While this might seem like a good survival tactic, it’s actually better to drink when you’re thirsty. Rationing water can lead to dehydration. Instead of rationing, try writing a heartfelt plea to the water gods or perfecting your rain dance.

Q: If I drink a lot of beer, can I count that towards my daily water intake? A: While this might sound like an absolute dream for some campers, beer, or any alcohol, actually dehydrates you rather than hydrates. So, if your camping trip seems like a great opportunity to drink the equivalent of a small lake in beer, you might want to reconsider. Or at least match every pint with an equal amount of water. Cheers to hydration!

Q: I heard cacti store water. Can I drink that if I run out? A: Yes, cacti do store water, but no, you can’t just pop a straw in there and enjoy a refreshing drink. Many cacti have bitter water that can make you sick, not to mention those pesky spines that don’t make for a pleasant user experience. Unless you’re an experienced survivalist or a very thirsty armadillo, stick to the water you brought with you.


Q: Can I carry my water in any container? A: Well, if you’re into the rustic pioneer lifestyle, you could try carrying it in a hollowed-out gourd. However, for practical purposes, use clean, sturdy containers that you can seal shut. If you like living on the edge, glass can be an option, but for those less daring (and more sensible), stick to BPA-free plastic, stainless steel, or specially designed hydration bladders.

Q: What’s the best way to carry water while hiking? A: There’s no one-size-fits-all answer here, but a good rule of thumb is: whichever way annoys you the least. Hydration packs are a great hands-free option, while some prefer the old-fashioned simplicity of a water bottle in the side pocket of a backpack. Just remember to keep it accessible. You don’t want to have to unpack your entire bag every time you need a sip.

Q: Should I carry water for my pets while camping? A: Absolutely, unless your pet is a cactus or a camel, in which case, you do you. For dogs and other furry companions, a good guideline is to bring an extra liter of water per day. And no, Fido doesn’t count towards your beer allowance. I bring a water bottle and found my dog easily drinks from it.

Remember, a well-hydrated camper is a happy camper. So, drink up, enjoy the great outdoors, and try not to confuse your water bottle with your bug spray. It doesn’t end well.
