Visiting the mountains is an unforgettable experience—but high elevation can affect everyone differently. Breckenridge and Keystone sit well above sea level, and guests traveling from lower elevations may experience mild altitude-related symptoms during their first day or two. This guide is designed to help you recognize common signs, ease your transition, and know exactly where to go if you need medical support—so you can relax, acclimate, and enjoy your stay with confidence.

If symptoms persist, worsen, or feel severe, professional medical care is recommended. Immediate care is advised for severe headaches, confusion, chest tightness, difficulty breathing, or persistent vomiting.
