Skiing Colorado's High Altitude Resorts

Currently many are planning the winter ski and snowboard trips. Do you live a relatively low altitudes but like to ski? If so, has that altitude been an issue for you?

I see people all the time who have issues with the altitude. Sometime its minor, like a headache, but other times it is more severe.

The Rockies, including Colorado, is home to some of the highest ski resorts in North America, with many base areas sitting above 8,000 feet and summits reaching well over 12,000 feet. While the scenery and snow are spectacular, the thin mountain air can affect even experienced skiers. As a Ski Instructor I see many people who come to ski with us from areas of the country at much lower altitudes (close to sea level some times). Sometimes they are affected by the altitude in one way or another. Here are some practical tips to help you stay comfortable, safe, and make the most of your ski trip.

1. Give Yourself Time to Acclimate

If you're traveling from a lower elevation, consider spending your first night at a lower altitude before heading to the highest resorts. Even taking it easy on your first ski day can help your body adjust to the thinner air.

2. Stay Hydrated

High altitude and cold, dry air increase fluid loss, even if you don't feel sweaty.

Hydration tips:

• Drink water throughout the day, not just when you're thirsty.

• Carry a reusable water bottle or hydration pack.

• Limit excessive caffeine and alcohol, especially during your first couple of days.

3. Watch for Altitude Sickness

Some visitors experience mild altitude sickness during their first day or two.

Common symptoms include:

• Headache

• Fatigue

• Dizziness

• Nausea

• Shortness of breath

• Difficulty sleeping

If symptoms become severe or worsen, stop skiing and seek medical attention.

4. Pace Yourself

Skiing at high altitude requires more energy because your muscles receive less oxygen.

Instead of trying to ski nonstop:

• Take regular breaks.

• Start with easier runs.

• Build up to more challenging terrain once you feel acclimated.

5. Protect Yourself from the Sun

UV exposure increases with elevation, and snow reflects sunlight back toward your face.

Don't forget:

• Broad-spectrum SPF 30+ sunscreen

• SPF lip balm

• UV-protective ski goggles

• A helmet-compatible hat or buff for exposed skin

Reapply sunscreen throughout the day, especially after lunch.

6. Dress in Layers

Mountain weather can change quickly, sometimes within minutes.

A simple layering system includes:

• Moisture-wicking base layer

• Insulating mid-layer

• Waterproof, breathable ski jacket and pants

Layers allow you to stay comfortable as temperatures and activity levels change.

7. Eat Regularly

Your body burns more calories at altitude and while skiing.

Pack easy-to-carry snacks like:

• Trail mix

• Energy bars

• Dried fruit

• Nuts

• Peanut butter sandwiches

Frequent snacks help maintain your energy throughout the day.

8. Expect the Weather to Change Quickly

Colorado weather is famously unpredictable. A sunny morning can quickly turn into snowfall or strong winds. Check the forecast before heading out and carry an extra layer if conditions are expected to change.

9. Warm Up Before Your First Run

Cold muscles are more prone to injury.

Spend a few minutes:

• Stretching your legs and hips

• Walking around in your boots

• Taking an easy warm-up run before tackling steeper terrain

10. Know Your Limits

High altitude can make even familiar terrain feel more demanding.

If you're feeling unusually tired or short of breath:

• Slow down.

• Take a break.

• Head indoors if necessary.

There's no benefit to pushing through exhaustion.

11. Keep Electronics Warm

Cold temperatures drain batteries much faster.

To extend battery life:

• Store your phone in an inside pocket close to your body.

• Carry a portable power bank.

• Keep spare camera batteries warm until you need them.

12. Stay Weather-Aware

Colorado resorts occasionally experience:

• High winds

• Snow squalls

• Whiteout conditions

• Temporary lift closures

Pay attention to resort alerts and always respect trail closures and safety signs.

13. Get Plenty of Rest

Many visitors underestimate how tiring high altitude can be. Aim for a full night's sleep before skiing, and don't be surprised if you feel more fatigued than usual during the first day or two.

14. Consider Travel Timing

If possible, arrive a day before you plan to ski. Giving yourself time to rest, hydrate, and acclimate can make your first day on the slopes much more enjoyable.

Final Thoughts

Colorado's high-altitude ski resorts offer incredible snow conditions, breathtaking mountain views, and unforgettable terrain. By staying hydrated, pacing yourself, protecting against the sun, and allowing time to acclimate, you'll be better prepared to enjoy everything the mountains have to offer. A little preparation goes a long way toward ensuring your Colorado ski adventure is memorable for all the right reasons.
