An altitude level is generally considered "too high" when it exceeds 8,000 feet (about 2,400 meters) above sea level, where many people start experiencing symptoms of acute mountain sickness (AMS). At altitudes above 12,000 feet (3,600 meters), the risk increases significantly, and extended stays can lead to more severe altitude-related illnesses. Individual tolerance can vary, so some may experience symptoms at lower altitudes. It's essential to acclimatize gradually and be aware of personal limits.
