Water is the most important survival necessity, and a general rule of thumb is to drink 2 liters of water a day or more, especially if you are in very hot climates. If you're staying at a campground in front of the field, filling a pitcher with water is one of the first things to consider when you arrive. How much water is enough to take on a camping trip? A good rule of thumb is to bring two gallons of water, or about seven and a half liters, per person per day of camping. How much water should you bring to the campsite? Bring at least two gallons of water per person per day to drink, cook and bathe when you are camping.
You can expect to need at least 1 gallon (3.75 liters) of water per person, per day of travel. So how much water to bring when camping, you ask? When camping in a car somewhere without water, you should plan to carry 2 gallons of water per person per day. When camping in nature, you should plan to carry one gallon of water per person per day. Since no one else is helping, I will do my best.
On a typical day, the average recommended amount of water per person will be 64 ounces. This is a rough estimate for an average person. If you're bigger, pack more. If you're smaller, pack less.
Depending on the heat, you may end up sweating a lot from the water. I would recommend no less than. How hot do you expect it to be? A gallon per person per day sounds good for people who are active in hot weather. Colder weather or lower levels of activity can lower that number.
I carry a rigid 5-gallon water container for most of my camp. Many camps will have wells to take advantage of. My suggestion is to bring a few 2-gallon jugs per person (some people will drink more, others will drink less and it will get even). Freeze half of the water and put it in the cooler instead of ice.
Bring a 2- to 3-gallon pot. If you start to run out of water, bring a pot of water to a boil and then, when it cools down, refill the empty bottles. If the lake water tastes bad, bring a few packs of powdered gatoraide, or bring oranges and store the peels, put the peels in the water when you boil it and it will taste a little citrus. Unless you're going to a remote location, most state parks have water fountains or other places where you can refill water for free.
Therefore, a good rule of thumb is to drink at least one gallon of drinking water and another gallon of other necessities. This is a rough estimate of person per day. To summarize the question of how much water you should bring when camping, as an adult, you need about 64 ounces of water on an average day. When I camp in the wild, the amount of water I carry to camp decreases dramatically, since I simply don't have the capacity to carry an additional 64 ounces of water when hiking.
If you somehow manage to bring in a lot of extra water, you can take a walk around the campsite and see if someone else forgot to bring enough or if they're running out. Even if there is access to drinking water, I always like to bring some of my own water from home to drink. But what happens if you end up with too much water to carry? Well, to avoid carrying too much weight, I suggest you go to a campsite that is accessible by car. Carrying this amount of water means you must have enough drinking water, water for cooking, cleaning and personal hygiene.
