Do you ever feel dizzy, unbalanced or weak on your first days skiing at altitude? About half of unacclimatized visitors to 10,000 feet get altitude sick.
Ski areas in Colorado, Utah, Wyoming, New Mexico, and Montana are more than high enough to cause altitude sickness.
Even the bases of these areas range from 8,000 – 9,600 feet – enough to cause 25% – 35% of visitors to get altitude sick. Must most of the skiing at Colorado resorts is in the range of 10,000 – 11,500 feet where a combination of exercise and altitude result in a 50% incidence of acute mountain sickness to the unacclimatized.
On your first day stay a bit lower and make that first day easy to avoid the headache, nausea and sleeplessness that can come from acute mountain sickness. If you can’t resist going higher and skiing like you mean it, then consider sleeping as low as possible or in an oxygenated room.
