AMS stands for Acute Mountain Sickness — a condition caused by ascending to high altitudes faster than your body can adapt to the reduced levels of oxygen.
It’s common on high-altitude adventures like the Everest Base Camp trek, Kilimanjaro, Mera Peak, and winter ascents of Toubkal, especially if proper acclimatisation isn’t followed.
Mild symptoms of AMS may include:
Headache
Nausea or loss of appetite
Tiredness or poor sleep
Dizziness or general fatigue
These symptoms are usually manageable and are the body’s way of saying it needs more time to adapt.
While we can’t promise you won’t feel the effects of altitude, we design all our high-altitude itineraries around gradual acclimatisation — with built-in rest days and a slow, steady pace to give your body the best chance to adapt.
We also carry out twice-daily health checks on all our high-altitude trips:
At breakfast and dinner, we’ll check your resting heart rate and oxygen saturation
We’ll ask about any symptoms and monitor changes over time
If needed, we’ll adapt the plan to prioritise your safety and wellbeing
Our team is trained to spot the early signs of AMS and act quickly to keep you safe — often before you even notice something’s off.
Most cases of AMS are mild and easily avoided with a well-planned itinerary, good hydration, and rest. Our team is there to support you every step of the way.
