Elk hunters in Colorado — do I need to worry about altitude sickness?

April 5, 2026

Quick Answer

Altitude sickness is a concern for elk hunters in Colorado, especially those above 10,000 feet, but can be mitigated with proper acclimatization and precautions.

Understanding Altitude Sickness

Altitude sickness, also known as acute mountain sickness (AMS), occurs when the body is unable to adapt to high elevations quickly enough. In Colorado’s elk hunting country, elevations above 10,000 feet are common, and AMS can be a concern for hunters. Symptoms include headache, nausea, fatigue, and shortness of breath.

Prevention and Acclimatization

To minimize the risk of AMS, hunters should acclimatize to the elevation by gradually increasing their exposure over a 24- to 48-hour period. For example, if planning to hunt at 11,000 feet, spend the first night at 9,000 feet and ascend to the higher elevation the following day. Additionally, drink plenty of water, eat high-carbohydrate foods, and avoid strenuous activities.

Recognizing and Treating AMS

If symptoms of AMS occur, move to a lower elevation immediately. If the symptoms are mild, rest and hydration may be sufficient to alleviate them. For more severe cases, descend to a lower elevation and seek medical attention if necessary. Carry a personal locator beacon (PLB) or satellite phone in case of an emergency.
