High-Altitude Travel: Plan for Acclimatisation

Consider sleeping altitude

Altitude illness risk depends on elevation, ascent rate and individual factors. Fitness does not guarantee protection; allow time to acclimatise.

Seek individual medical advice

Discuss existing conditions, past altitude problems or concerns with a clinician before travel. Do not choose preventive medication based on a tourism page.

Speak up if you feel unwell

Report suspected altitude symptoms and seek medical advice rather than ascending to keep a schedule. Severe or worsening symptoms need urgent medical help.
