Kilimanjaro Safety & Health
Approximately 35,000 people climb Kilimanjaro each year. With proper preparation, the right route, and experienced guides, it is a safe trek. Here is everything you need to know about staying safe on the mountain.
Acute Mountain Sickness (AMS)
Altitude sickness is the primary health risk on Kilimanjaro. It occurs when your body cannot acclimatise fast enough to the decreasing oxygen levels at high altitude. At the summit (5,895m), there is roughly 50% of the oxygen available at sea level. AMS can affect anyone regardless of age, fitness, or previous altitude experience.
The single most effective prevention is choosing a longer route with proper acclimatisation. The difference in summit success between a 5-day route (27-45%) and a 9-day route (95-98%) is dramatic — extra days save climbs. This is why we recommend 7-9 day itineraries.
Mild AMS
- Mild headache
- Nausea or reduced appetite
- Fatigue or dizziness
- Difficulty sleeping
We monitor you closely, ensure you hydrate and eat, and adjust the pace. Mild AMS usually resolves with rest and time to acclimatise — no descent required at this stage.
Moderate AMS
- Persistent headache not relieved by painkillers
- Worsening nausea or vomiting
- Increasing weakness
- Reduced coordination
We stop ascending and reassess. Depending on pulse oximetry and symptom progression, we hold at altitude to acclimatise or begin a controlled descent. Diamox may be recommended if not already in use.
Severe AMS / HACE / HAPE
- Confusion or altered consciousness
- Loss of coordination (ataxia)
- Breathlessness at rest
- Persistent cough with frothy sputum
This is an emergency. We initiate immediate supervised descent, administer emergency oxygen, and arrange helicopter evacuation if needed. Descent is the only definitive treatment for HACE and HAPE.
How We Keep You Safe
Longer Routes = Higher Success
We recommend 7-9 day itineraries with built-in acclimatisation days. Our routes use the 'climb high, sleep low' strategy — ascending to a high point during the day, then descending to sleep at a lower altitude.
Daily Health Monitoring
Our guides check your pulse oximetry (blood oxygen saturation and heart rate) every morning and evening. We use the Lake Louise Scoring System to assess AMS symptoms objectively — not just 'how do you feel?'
Pole Pole Pacing
'Slowly, slowly' in Swahili. Our guides maintain a deliberately slow pace that keeps your heart rate in the aerobic zone. If you're breathing hard, you're going too fast. Proper pacing is the most underrated safety measure on Kilimanjaro.
Hydration & Nutrition
We ensure 3-4 litres of water per day per climber. Our mountain cook prepares calorie-rich meals with emphasis on carbohydrates — the most easily digested fuel at altitude. We monitor food intake and intervene if a climber stops eating.
Wilderness First Aid Certified
All our lead guides hold Wilderness First Aid (WFA) certification — rigorous emergency medicine training for remote settings. They are trained to recognise AMS, HACE, and HAPE and to initiate appropriate emergency response.
Emergency Evacuation
We carry emergency oxygen, satellite communication, and stretcher equipment on every climb. Helicopter evacuation can be arranged within hours from any point on the mountain. All climbers must carry travel insurance covering high-altitude evacuation.
Safety Equipment on Every Climb
- Emergency bottled oxygen
- Pulse oximeters for daily monitoring
- Comprehensive high-altitude first aid kit
- Portable stretcher for evacuation
- Satellite phone for emergency communication
- Automated external defibrillator (on premium climbs)
- Gamow bag (portable hyperbaric chamber) on request
- Wilderness First Aid certified lead guides
Diamox (Acetazolamide)
Diamox (acetazolamide) is a prescription medication that helps prevent altitude sickness by stimulating breathing and increasing blood oxygen levels. It is the most commonly used preventive medication for high-altitude trekking.
How It Works
Diamox acidifies the blood, which stimulates breathing and improves oxygen absorption. It speeds up natural acclimatisation. The typical dose is 125-250mg twice daily, starting 1-2 days before ascending above 2,500m.
Side Effects
Common side effects include tingling in fingers and toes, increased urination, and altered taste of carbonated drinks. These are harmless. Rare but serious: allergic reaction in people with sulfa allergies. Always consult your doctor before taking Diamox.
Important: Diamox is a preventive aid, not a substitute for proper acclimatisation. It works best in combination with a longer route (7-9 days), proper hydration, and slow pacing. Do not use Diamox to mask symptoms and continue climbing — this is dangerous.
Porter Welfare Standards
The safety and dignity of our mountain crew is as important as the safety of our climbers. Approximately 50,000 porters work on Kilimanjaro each year, and their welfare varies dramatically between operators. We hold ourselves to the highest standards.
Fair Wages
We pay above KINAPA recommended rates. Porters receive their wages directly — not through intermediaries.
Weight Limits
Maximum 20kg per porter (KINAPA regulation). We weigh all loads at the gate and redistribute if needed.
Proper Equipment
We provide sleeping tents, sleeping mats, and warm clothing for all porters. No porter sleeps outside.
Nutrition
Three hot meals per day for all crew members. Same quality food as our climbers.
