How to Beat Altitude Sickness: A Local's Guide to Summit County

Almost everyone who visits Summit County from low elevation feels something in the first 24 to 48 hours. Headache, fatigue, shortness of breath, not sleeping well. It doesn't matter how fit you are or how many times you've been here before. Breckenridge sits at 9,600 feet. Keystone is at 9,300 feet. Frisco is over 9,000 feet. That's a serious jump from Denver, let alone sea level, and your body needs time to catch up.

The good news is that altitude sickness is manageable, and knowing what to actually do makes a huge difference. Here's what locals know and what the internet usually gets half right.

What Altitude Sickness Actually Feels Like

Acute mountain sickness, which is the technical name for altitude sickness, usually hits within the first few hours of arriving at elevation. The most common symptoms are a dull headache, fatigue that feels disproportionate to what you've done, nausea, dizziness, and waking up in the middle of the night unable to sleep. Some people feel it hard. Some people barely notice. There's no reliable way to predict who will be affected, and being in great shape doesn't protect you.

Most people feel significantly better by day two or three as their bodies adjust. The key is not to make it worse on day one.

Before You Even Leave Home

Start hydrating before you get here. Most people are already mildly dehydrated when they land at Denver International and then drive straight up to 9,000 feet. That combination makes everything worse. Drink extra water the day before your trip and cut back on alcohol.

If you're coming from sea level and you're prone to altitude issues, talk to your doctor about Diamox (acetazolamide). It's a prescription medication you start 24 hours before arriving at altitude and it genuinely works for a lot of people. Worth a conversation with your doctor before you go, especially if you've struggled with altitude before.

The First 24 Hours Matter Most

This is where most visitors go wrong. You get here, you're excited, you want to ski hard or hike or go out for drinks. Day one is not the day for any of that.

Take it easy on arrival day. Walk around. Let your body start adjusting. Eat lighter than normal and skip the big salty mountain meal until day two. And seriously consider skipping alcohol or keeping it to a minimum your first night. Alcohol dehydrates you and hits harder at altitude. It's the single fastest way to guarantee a rough next morning.

Drink water constantly. More than you think you need. Altitude is drying and your body is working harder than usual.

What Actually Helps

Water is the most important thing, consistently. Aim for more than your normal daily intake.

Ibuprofen works well for altitude headaches. It's the first thing most locals recommend.

If you want an over-the-counter option, there are altitude adjustment supplements available at local pharmacies and outdoor retailers in Breckenridge. Some people swear by them, some don't notice a difference. Worth trying if you're sensitive to altitude.

Oxygen bars and canned oxygen are available in Breckenridge and can give temporary relief if you're really struggling. It's not a cure, but it helps you feel human again while you're acclimating.

Rest when you need to. The people who push through day one and crash on day two are a Summit County tradition. Don't be that person.

What Doesn't Help

Caffeine is a diuretic. Coffee first thing in the morning at altitude is fine, but leaning on it to feel more awake when you're actually just altitude-tired usually backfires.

Alcohol on day one, as mentioned, makes everything harder. It disrupts your sleep at altitude, dehydrates you, and worsens every symptom.

And despite what you may have heard, fitness level is not a reliable predictor of how you'll handle altitude. Incredibly fit people get hit hard. Less fit people sail through. It's largely physiological and not something you can train away.

When to Actually Worry

Regular altitude sickness resolves within a few days of acclimation. But if someone in your group develops confusion, loses coordination, has a persistent severe headache that doesn't respond to ibuprofen, or has significant difficulty breathing at rest, those are signs of High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE), which are serious conditions. The treatment is to descend to lower elevation immediately and seek medical care. Frisco and Breckenridge have urgent care options, but descent is the most important step.

One More Thing Locals Know

If you're really struggling on day one and you have flexibility, driving down to sleep in Denver or at a lower elevation and coming back up the next morning can reset things considerably. It feels counterintuitive when you're excited to be in the mountains, but it works.

Summit County will still be here tomorrow. Give your body a chance to catch up and you'll enjoy it a lot more.
