It’s crucial to stay hydrated while traveling, particularly when you’re at the airport for hours. Luckily, Denver International Airport (DEN) makes it budget-friendly with several completely free and easily reachable water bottle refill stations throughout the terminals.

In this guide, you’ll learn everything you need to know about finding free water sources at Denver Airport.

Where Can I Find the Free Refill Stations?

To improve the passenger experience, Denver Airport offers multiple water bottle refill stations in all three main concourses: A, B, and C. These stations are usually located near restrooms or waiting areas, making them easy to find.

There are approximately four refill stations per concourse, so you won’t need to walk far to find one.

 Location Overview:

  • Concourse A: Stations are located past security near various gates. Ideal for passengers traveling on domestic or international flights from this terminal.
  • Concourse B: Refill points can be found near restrooms and central areas.
  • Concourse C: Conveniently located near dining and gate areas.

Why Does This Matter?

At Denver’s high altitude, your body dehydrates more quickly than at sea level. Drinking enough water before and after your flight can:

  • Minimize the effects of jet lag
  • Support your immune system
  • Avoid skin dryness
  • Help maintain your energy levels

Denver’s tap water is also safe and great-tasting, tested regularly to meet U.S. quality standards, so you can drink with assurance.

Bring Your Own Bottle

You can easily pass through security at Denver Airport with an empty water bottle—no problem at all. After the checkpoint, just head to one of the refill stations and fill up for free.

It’s a smart, eco-friendly choice that helps reduce plastic waste, too.

Is Buying Bottled Water Worth It?

Not at all! A bottle of water from an airport shop or vending machine can set you back $4 to $6 or more. Instead, just use the free refill stations and keep your water bottle topped up at no extra cost.

Extra Tips for Hydration at the Airport

  • Don’t wait until you’re thirsty. Drink water regularly, especially if you’re flying long distances.
  • Refill right before boarding. That way you’ll have fresh water during your flight, especially on budget carriers that charge for drinks.
  • Encourage others to refill too. It’s a simple step toward more sustainable air travel.

No Bottles Needed: Just Refill and Go

If you’re traveling via Denver International Airport, you don’t have to spend money on bottled water or worry about staying hydrated. Thanks to free, clean, and easily accessible refill stations, travelers can keep their bottles full and stay hydrated during their travel.

Just bring an empty bottle in your carry-on, and you’re ready to take advantage of one of the airport’s most underrated amenities.
