Altitude Sickness on Mount Kenya

Altitude Sickness on Mount Kenya: Symptoms, Prevention & Safety Tips. Trekking Mount Kenya is an unforgettable adventure. But as you climb higher, the risk of altitude sickness becomes real. Whether you’re aiming for Point Lenana or preparing for a technical climb to Batian or Nelion, understanding and preventing altitude sickness is essential for a safe and successful trek.

This guide from Ahambi Tours explains what altitude sickness is, when it can affect you on Mount Kenya, and how to prevent it.

What is Altitude Sickness?

Altitude sickness, also called Acute Mountain Sickness (AMS), occurs when your body struggles to adjust to low oxygen levels at high elevations. Symptoms typically begin above 2,500m, and Mount Kenya’s trekking routes reach as high as 4,985m at Point Lenana.

Can You Get Altitude Sickness on Mount Kenya?

Yes. Although Mount Kenya is not as high as Mount Kilimanjaro or Everest, it still presents a risk of altitude sickness, especially for those who ascend too quickly or don’t acclimatize properly.

Altitude sickness is most common on short treks or routes with steep altitude gains like Naro Moru. Even fit and healthy trekkers can experience AMS.

At What Altitude Does Sickness Start on Mount Kenya?

Altitude sickness can begin as low as 3,000m. The key elevation points on Mount Kenya include:

• Sirimon Gate: 2,650m
• Old Moses Camp: 3,300m
• Shipton’s Camp: 4,200m
• Point Lenana Summit: 4,985m

As you climb higher, oxygen levels decrease, increasing the chances of AMS.

Symptoms of Altitude Sickness While Trekking Mount Kenya

Typical symptoms include:

• Headache
• Nausea or vomiting
• Dizziness or lightheadedness
• Shortness of breath
• Loss of appetite
• Difficulty sleeping
• Fatigue

If symptoms worsen, it may develop into more serious conditions like High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE), which are medical emergencies.

Who Is Most at Risk of Altitude Sickness?

Anyone can develop AMS, regardless of age or fitness level. You’re at higher risk if:

• You ascend rapidly without rest days
• You have a history of AMS
• You do not hydrate or eat properly
• You ignore early symptoms

How to Prevent Altitude Sickness on Mount Kenya

1. Trek Slowly: The golden rule is “Pole pole” – take it slow and steady. Rapid ascents increase your risk.
2. Choose a Longer Trek: 5 to 6-day itineraries allow time to acclimatize. Avoid rushing the summit.
3. Stay Hydrated: Drink 3 to 4 liters of water daily. Avoid alcohol and caffeine which can cause dehydration.
4. Eat Well: Consume energy-rich meals. Trekking burns calories, and your body needs fuel to acclimatize.
5. Listen to Your Body: If you feel symptoms, rest. Don’t ascend further until they subside.
6. Use Diamox (Optional): Some trekkers use Acetazolamide (Diamox) to prevent or reduce AMS symptoms. Speak to your doctor before your trip.
