If you're planning a vacation in the breathtaking high country of Colorado, you're in for fresh air, stunning scenery, and unforgettable adventures. But there's one thing that often surprises visitors—just how important hydration becomes at higher elevations.

Whether you're heading to Breckenridge, Vail, Aspen, or any of the amazing mountain towns Colorado has to offer, staying hydrated is one of the easiest and most effective ways to feel your best and make the most of your trip.

Why Hydration Is So Important in Colorado’s High Elevations

At elevations above 8,000 feet, your body begins to react differently than it does at sea level. The air is thinner, drier, and holds less oxygen. This can lead to a condition known as altitude sickness—symptoms of which include headaches, fatigue, nausea, and dizziness.

One of the biggest culprits behind altitude sickness is dehydration. The low humidity in the mountains causes your body to lose water more quickly, even while at rest. Add hiking, skiing, or mountain biking to the mix, and that water loss increases significantly.

Common Signs of Dehydration at High Altitude

• Dry mouth and lips
• Headaches
• Fatigue or sluggishness
• Dizziness or lightheadedness
• Nausea
• Dark-colored urine

Hydration Tips for Your Colorado Vacation

1. Start Hydrating Before You Arrive
Begin drinking more water a few days before your trip. Staying hydrated in advance helps your body adjust more smoothly to the altitude once you arrive.

2. Drink More Than You Think You Need
Aim for at least 3-4 liters of water per day while at altitude—especially if you're hiking, skiing, or being active. Thirst isn't always a reliable indicator, so sip water regularly throughout the day.

3. Limit Alcohol and Caffeine
Both are diuretics and can contribute to dehydration. If you’re enjoying a Colorado craft beer or coffee, try to balance it with a glass of water for every drink you consume.

4. Pack a Refillable Water Bottle
Bring a reusable water bottle with you everywhere. Many Colorado towns and trailheads offer water filling stations, and having water on hand makes it easier to stay on track.

5. Include Electrolytes
Water is essential, but your body also needs electrolytes like sodium and potassium—especially after sweating. Bring along electrolyte packets or sports drinks for extra support.

6. Eat Hydrating Foods
Fruits and vegetables like cucumbers, oranges, berries, and watermelon have high water content. Snack smart and support hydration with your diet.

7. Take It Easy on Day One
Let your body acclimate. If you're arriving from sea level, avoid high-exertion activities on your first day and give your system a chance to adjust—with plenty of water, of course.

Make the Most of Your Colorado Adventure

Hydration isn’t just about avoiding altitude sickness—it’s about maximizing your energy and enjoying every moment of your Colorado vacation. Whether you're exploring alpine trails, carving fresh powder, or just soaking in the views, your body will thank you for keeping it fueled with water.

So before you lace up your hiking boots or strap into your snowboard, remember: drink up, stay hydrated, and thrive at altitude.
