High altitude must haves for your next trip

Traveling to high altitude destinations like Cusco, La Paz, or Lhasa requires preparation. Altitude sickness can hit anyone — even fit, experienced travellers — so having the right gear before you go can make the difference between a miserable trip and a great one. Here's what to pack.

1. Altitude sickness prevention

Your first line of defence is prevention. Start before you even land. If you're heading somewhere above 2,500m, speak to your doctor about Acetazolamide (Diamox), a prescription medication that speeds up acclimatisation. For over-the-counter options, these products have strong reviews from high-altitude travellers:

3. Hydration and acclimatisation

Staying hydrated is one of the most effective things you can do at altitude. Thin, dry mountain air pulls moisture from your body faster than you'd expect, and dehydration makes altitude symptoms like headaches and fatigue much worse. Aim for 3–4 litres of plain water per day — more if you're hiking or exerting yourself — and sip steadily throughout the day rather than drinking it all at once. Limit alcohol and caffeine for the first 24–48 hours after arrival, since both are diuretics that work against acclimatisation. Consider adding an acclimatisation drink mix to support your body as it adjusts.
