Learn how to calculate how much water to take on a hike and how best to store it; plus some helpful safety tips for filling up bottles and bladders..
When planning a hike, one of the most critical aspects to consider is how much water to take with you. The importance of carrying the right amount of water cannot be overstated.
Proper hydration is essential for maintaining energy levels, cognitive function, and overall physical health during a hike.
Failing to bring enough water can lead to serious consequences, including dehydration, heatstroke, and other potentially life-threatening conditions.
This article will guide you on how to calculate the appropriate amount of water to carry based on the duration and difficulty of your hike.
Additionally, we’ll cover the best practices for hydrating effectively, recognizing signs of dehydration, and filtering water in the wild.
For those interested in exploring different outdoor adventures, learning about the popular types of hiking can help you choose the best experience for your next journey.
How to Come Up With a Water Carry Plan
The first step in ensuring you have enough water for your hike is to come up with a water carry plan.
This involves estimating how much time your hike will take and calculating your water needs based on that estimate.
A general rule of thumb is to carry 1 liter of water for every 2 hours of hiking. However, the actual amount of water you need can vary depending on factors such as temperature, humidity, and the intensity of the hike.
To estimate how long it will take you to complete your hike, use the benchmark that it takes an average hiker about 30 minutes to walk a mile on flat terrain.
If your hike involves significant elevation changes, refer to your topographical map and add another 30 minutes for every 1,000 feet of elevation gain.
For example, if you’re planning a 6-mile hike with a 1,000-foot elevation gain, the calculation would be as follows:
- 6 miles x 30 minutes = 3 hours
- Add 30 minutes for elevation gain = 3.5 hours
Based on the rule of thumb of 1 liter of water for every 2 hours of hiking, a 3.5-hour hike would require 1.75 liters of water. It’s always a good idea to round up and carry a little extra water just in case of unexpected delays or challenges.
How to Hydrate Properly
Proper hydration is key to staying healthy and performing well on a hike. It’s important to understand not only how much water to carry but also how to hydrate effectively.
While energy drinks can be helpful in providing a quick boost of energy, they are not always the best choice for hydration.
Many energy drinks contain high levels of sugar and caffeine, which can lead to dehydration rather than preventing it.
Instead, consider using electrolyte-replacement drinks that are low in sugar. These drinks help replenish the electrolytes lost through sweat without contributing to dehydration.
Water remains the most effective way to stay hydrated during a hike. Based on the general rule of thumb mentioned earlier, you should aim to drink approximately half a liter of water per hour of hiking. This amount may need to be increased if you are hiking in hot or humid conditions.

It’s also important to drink small amounts of water frequently rather than large amounts infrequently. This helps your body absorb the water more efficiently and reduces the likelihood of gastrointestinal distress.
Remember that by the time you feel thirsty, you may already be dehydrated, so it’s essential to drink water regularly, even if you don’t feel thirsty.
Signs and Symptoms of Dehydration
Dehydration can be dangerous, especially when it sneaks up on you quietly during a hike. It can strike without notable warnings, making it crucial to be aware of the signs and symptoms. Recognizing these early on can help you take action before it becomes a serious issue.
The most common signs and symptoms of dehydration include:
- Headache: Dehydration can cause a throbbing headache as your body struggles to maintain normal functions.
- Extreme thirst: Feeling very thirsty is a clear sign that your body needs more water.
- Cramps: Dehydration can lead to muscle cramps, especially in your legs and arms, due to the loss of electrolytes.
- Nausea: As dehydration progresses, it can cause nausea and even vomiting.
- Dizziness: Feeling lightheaded or dizzy can indicate that your body is not getting enough fluids.
- Fatigue: Dehydration saps your energy, making you feel unusually tired and weak.
- Dark urine: One of the most telling signs of dehydration is dark yellow or amber-colored urine, indicating that your body is conserving water.
If you notice any of these symptoms while hiking, it’s important to stop, rest, and drink water immediately. In severe cases, you may need to seek medical attention.
Best Methods and Equipment for Carrying Water When Hiking
Carrying water on a hike can be done in various ways, and the method you choose will depend on the length of your hike, the terrain, and your personal preference.
One of the most popular methods is using a hydration pack. These packs are designed with a water bladder and a drinking tube, allowing you to sip water easily while on the move.
Hydration packs are great for long hikes as they distribute the weight evenly across your back and keep your hands free.
Another option is to carry water bottles. Water bottles are versatile and come in various sizes and materials. Some hikers prefer insulated bottles that keep water cool for longer periods, especially during hot weather hikes.
For shorter hikes or as an additional water source, consider bringing a squirt bottle. These bottles are convenient for quick sips and can also be used to spray water on your face or neck to cool down.
How To Filter Water In The Wild
Most natural water sources are not safe to drink without some form of filtration, as they can contain harmful bacteria, viruses, and parasites.
Fortunately, there are several ways to filter water in the wild, ensuring it is safe to drink. One of the most reliable methods is using a portable water filter or purification system.
These devices are designed to remove contaminants from water, making it safe to drink. Some popular options include pump filters, squeeze filters, and straw filters.
If you don’t have a filtration device, boiling water is another effective method. Boiling water for at least one minute kills most pathogens, making it safe to drink.
However, this method requires you to carry a stove and fuel, which may not be practical for all hikes.
Chemical treatments, such as iodine tablets or chlorine dioxide drops, are also an option. These treatments are lightweight and easy to carry, making them a good backup option.
However, they can leave an unpleasant taste in the water and may take some time to work.
In Conclusion
Carrying enough water on a hike is crucial for your safety and enjoyment. By planning ahead, knowing how to hydrate properly, and being aware of the signs of dehydration, you can ensure a successful and enjoyable hiking experience.
Whether you’re using a hydration pack, water bottles, or portable filtration devices, make sure you’re well-prepared and have enough water to stay hydrated throughout your hike.
