Altitude can be a concern during short day trips to high mountain passes, especially above 3,000 meters.
Rapid elevation gain
Routes toward areas such as Khunjerab Pass involve rapid elevation gain within a few hours.
Possible short-term symptoms
Even brief exposure to high altitude may cause headache, dizziness, or fatigue in sensitive individuals.
Reducing risk
Spending previous nights at moderate elevation and limiting physical exertion at the highest point helps reduce discomfort.
