For most hikes, water is the best drink. On longer, hotter, or more strenuous hikes, an electrolyte drink can also be useful to help replace sodium and other minerals lost through sweat.
I remember bringing only a sugary sports drink on one of my first long hikes because I thought it would give me more energy than water. By the middle of the day, I was tired of the sweetness and still wanted plain water. Since then, I've learned that hydration doesn't need to be complicated. Most of the time, water does the job perfectly well, and electrolytes are something to add when the conditions actually call for them.
The best hiking drink is the one that keeps you hydrated without upsetting your stomach.
The Short Answer
For most hikers, the best drink is:
-
Water for regular day hikes
-
Water plus electrolytes for long, hot, or strenuous hikes
You usually don't need energy drinks or heavily sweetened beverages unless you have a specific reason for using them.
1. Water Is the Best Everyday Choice
For shorter and moderate hikes, plain water is usually enough.
Water helps support:
-
Hydration
-
Temperature regulation
-
Physical performance
-
Concentration
It's simple, refreshing, and easy to carry.
2. Electrolytes Can Help on Longer Hikes
If you're hiking for several hours, sweating heavily, or dealing with hot weather, an electrolyte drink may be helpful.
Electrolytes can help replace minerals such as:
-
Sodium
-
Potassium
You don't necessarily need to replace all of your water with an electrolyte drink. Many hikers carry water and add electrolytes to one bottle.
3. Don't Wait Until You're Extremely Thirsty
It's usually better to drink regularly throughout the hike rather than trying to catch up later.
Take small sips during:
-
Rest breaks
-
Climbs
-
Hot sections of the trail
Your exact fluid needs will vary depending on temperature, effort, body size, and how much you sweat.
4. Be Careful With Very Sugary Drinks
Some sports drinks contain a lot of sugar.
That isn't automatically bad during prolonged activity, but very sweet drinks can become unpleasant or cause stomach discomfort for some people.
If you prefer sports drinks, you may find a lighter electrolyte mix easier to tolerate.
5. What About Coffee or Tea?
Coffee and tea can contribute to your daily fluid intake, but I wouldn't make them your primary hiking drink.
They're better suited to:
-
Before the hike
-
A break at camp
-
After the hike
During the trail itself, water should usually remain your main source of hydration.
6. What About Energy Drinks?
Energy drinks generally aren't necessary for hiking.
They can contain large amounts of:
-
Caffeine
-
Sugar
-
Other stimulants
If you're tired on the trail, food, water, pacing, and rest are usually more important than reaching for a highly caffeinated drink.
How Much Should You Drink While Hiking?
There isn't one perfect amount for everyone.
Your needs depend on:
-
Weather
-
Hiking intensity
-
Distance
-
Body size
-
Individual sweat rate
A better approach is to start well hydrated, carry enough fluid for your route, and drink regularly according to thirst and conditions.
A Quick Aside About Hot-Weather Hiking
One thing I've learned is that hydration becomes much easier when you plan it before leaving. Knowing where you'll refill water, carrying enough for exposed sections, and packing electrolytes when it's hot can prevent a lot of unnecessary fatigue later in the day.
My Personal Takeaway
For most hikes, water is the best drink you can carry. If you're hiking for a long time, sweating heavily, or walking in hot conditions, adding electrolytes can be helpful. Keep it simple, drink regularly, and choose something your stomach already tolerates well. Good hydration should support your hike—not become another thing you have to think about.
