What Helps Altitude Sickness in Colorado?

Tips to Prevent and Treat Altitude Sickness While Visiting the Rockies

If you’re visiting Colorado and find yourself feeling dizzy, short of breath, or fatigued, you might be experiencing altitude sickness—a common reaction when the body struggles to adjust to the lower oxygen levels at higher elevations. Whether you're exploring Denver (5,280 feet), hiking in Breckenridge (9,600 feet), or vacationing in Grand Lake (8,369 feet), understanding how to prevent and treat altitude sickness can make or break your trip.

What Is Altitude Sickness?

Altitude sickness, also known as acute mountain sickness (AMS), occurs when you travel to a higher elevation too quickly. The lower oxygen levels at high altitudes can lead to symptoms such as:

• Headache

• Nausea

• Fatigue

• Shortness of breath

• Dizziness

• Insomnia

In more severe cases, altitude sickness can progress to High-Altitude Pulmonary Edema (HAPE) or High-Altitude Cerebral Edema (HACE), both of which require emergency care.

What Helps Altitude Sickness in Colorado?

1. Hydration Is Key

Colorado’s dry mountain air causes you to lose moisture faster through breathing and perspiration. Drink plenty of water—at least 3 to 4 liters per day. Avoid alcohol and caffeine in your first 24–48 hours, as they can dehydrate you further and worsen symptoms.

2. Ascend Slowly

If possible, plan a gradual ascent. Spend your first night in a lower-elevation city like Denver or Boulder before heading up into the mountains. This gives your body time to acclimate.

📍 Example: Spend a night in Estes Park (7,522 feet) before heading to Trail Ridge Road (12,000+ feet).

3. Eat a High-Carb Diet

Carbohydrates require less oxygen for metabolism than fats or proteins. Eating a high-carbohydrate diet—think fruit, rice, bread, and pasta—can give you more energy at altitude.

4. Take It Easy the First 24–48 Hours

Physical exertion in the first two days at altitude can aggravate symptoms. Try to rest, relax, and avoid strenuous hikes or activities until you know your body is adjusting.

5. Try Over-the-Counter Remedies

• Ibuprofen or acetaminophen can ease headaches.

• Anti-nausea meds like Dramamine or meclizine may help with queasiness.

• Electrolyte tablets or drinks (like Liquid I.V. or Gatorade) can replenish minerals lost due to dehydration.

6. Consider Prescription Medication

If you’re prone to altitude sickness or planning a rapid ascent:

• Ask your doctor about acetazolamide (Diamox), a medication that helps the body adjust faster.

• It’s typically taken 1–2 days before ascending and continued for a few days at altitude.

7. Portable Oxygen and Hyperbaric Bags

For those with ongoing symptoms or in remote areas:

• Portable oxygen canisters (sold at outdoor gear shops across Colorado) offer quick relief.

• Some mountain clinics and resorts also offer Gamow bags, which simulate lower elevation and are used in emergencies.

Bonus: Natural Remedies That May Help

While not medically proven, many visitors and locals swear by these options:

• Coca tea or coca candies (popular in Peru and Bolivia, sometimes found in specialty stores)

• Ginkgo biloba supplements (some studies show promise in reducing symptoms)

• Essential oils like peppermint or eucalyptus for nausea and headaches

When to Seek Medical Attention

If symptoms worsen or include:

• Trouble breathing at rest

• Confusion

• Chest tightness

• Inability to walk straight
  ...you should descend immediately and seek medical care. Emergency clinics in high-altitude towns like Vail, Frisco, or Aspen are equipped to handle altitude-related issues.

Colorado Elevation Reference Points

If you’re planning a trip through the Rockies, here’s how the elevation changes from city to mountain towns:

• Denver – 5,280 feet (The “Mile-High City”)
  Great for your first stop if you’re flying in from lower elevations.

• Estes Park – 7,522 feet
  A good halfway point to let your body adjust before higher climbs.

• Grand Lake – 8,369 feet
  Where The Grand Chalet is located — high enough to feel the thinner air if you come from sea level.

• Breckenridge – 9,600 feet
  A popular ski town where symptoms are more common for new visitors.

• Trail Ridge Road – 12,183 feet
  One of the highest paved roads in North America — acclimate first before driving this route.

What NOT to Do at Altitude

• Avoid alcohol for the first 24 hours.

• Don’t rely only on supplements — use proven hydration/rest strategies.

• Skip strenuous hikes until acclimated.

Final Tips for Enjoying Colorado’s High Elevations

• Plan extra time to acclimate if you're traveling from sea level.

• Pack smart with hydration tools, OTC meds, and warm clothing (temperatures drop fast at altitude).

• Listen to your body—it's better to miss one hike than cut your whole trip short.

Pro tip:

Altitude affects everyone differently. Even elite athletes can get sick if they ascend too fast. Kids and older adults are also vulnerable.

Frequently Asked Questions

How long does altitude sickness last in Colorado?
Most mild symptoms last between one and three days as your body adapts to the thinner air. Resting, staying hydrated, and taking it easy during the first 24–48 hours can help you adjust faster.

Does drinking water help altitude sickness?
Yes. Hydration is one of the most effective ways to prevent or reduce symptoms. Aim to drink at least three to four liters of water per day and avoid alcohol for the first 24 hours after arriving at higher elevations.

Can you get altitude sickness in Denver?
It’s possible, especially if you’re visiting from sea level. While Denver’s elevation (5,280 feet) is moderate, some travelers still experience mild symptoms like fatigue or shortness of breath during the first day.
