ALTITUDE & ACCLIMATISATION ON KILIMANJARO
Understand how altitude can affect your climb, why time to acclimatise matters, and which symptoms require action. Learn what to discuss before travelling and why speaking openly with your guide is essential throughout the journey.
ALTITUDE SYMPTOMS: SPEAK UP EARLY
Tell your guide promptly if you develop a headache, nausea, dizziness, unusual tiredness, or other symptoms after ascending. Do not ascend higher with symptoms of altitude illness. If symptoms worsen despite resting at the same altitude, descend with assistance.
Confusion, difficulty walking steadily, or breathlessness at rest are emergency warning signs. Alert your guide immediately: urgent descent and medical care are needed. Do not wait until morning or the next scheduled health check.
This guide provides general information. Discuss your health, itinerary, and any altitude medication with a qualified healthcare professional before travelling.
WHY YOUR BODY NEEDS TIME TO ADJUST
As you climb, air pressure falls and less oxygen is available with each breath. Your body needs time to respond to this change. Acclimatisation is that adjustment process; it cannot be replaced by determination or physical fitness alone.
WHAT IS ACCLIMATISATION?
Your body responds to reduced oxygen availability partly by increasing breathing. These adjustments take time, and you may still find exercise harder than at lower elevations.
A gradual ascent gives your body more opportunity to adjust. The elevation where you sleep and how quickly it increases are important—not just the pace at which you walk.
FITNESS DOES NOT PREVENT ALTITUDE ILLNESS
Being fit helps with the physical demands of trekking, but it does not protect you from altitude illness. Fit, experienced climbers can still become unwell.
Your response on a previous trip can help inform planning, but a successful past climb does not guarantee the same response next time. Report symptoms honestly, regardless of your experience or fitness.
ALTITUDE ILLNESS: SYMPTOMS THAT NEED ATTENTION
Report new symptoms after ascending, even if they seem minor. Altitude illness can begin with a headache and other symptoms, while changes in coordination, awareness, or breathing can signal an emergency. Do not wait for every symptom to appear.
ACUTE MOUNTAIN SICKNESS — AMS
After a recent ascent, a headache together with nausea, dizziness, unusual fatigue, or loss of appetite may indicate acute mountain sickness. Vomiting can also occur.
Tell your guide promptly and do not ascend higher with symptoms of altitude illness. Worsening symptoms despite rest at the same altitude require descent.
CONFUSION OR UNSTEADINESS — EMERGENCY
Confusion, difficulty walking steadily, unusual drowsiness, or reduced awareness can indicate high-altitude cerebral oedema (HACE), a life-threatening condition affecting the brain.
Alert your guide immediately. Urgent assisted descent and emergency medical care are needed. Do not leave the person alone or wait until morning.
BREATHLESSNESS AT REST — EMERGENCY
Breathlessness while resting, a worsening cough, chest congestion, or a marked decline in walking ability can indicate high-altitude pulmonary oedema (HAPE), a life-threatening condition involving fluid in the lungs. It can occur without preceding AMS.
Alert your guide immediately. Urgent assisted descent and emergency medical care are needed, with exertion kept to a minimum.
WHAT DOES THE WEATHER FEEL LIKE?
Conditions change as you climb and can shift during the same day. You may feel warm while walking in sunshine, then cool quickly when clouds arrive, the wind rises, or you stop. Keep extra layers and waterproof clothing accessible in your daypack.
SUN, CLOUD & RAIN
Sunshine can feel warm while you walk, but cloud, rain, and wind can quickly change your comfort. Keep waterproof layers accessible and protect the contents of your bags from moisture. Use sunglasses, sunscreen, and a sun hat even when the air feels cool.
COLD EVENINGS & HIGH CAMPS
Once you stop walking, you may cool down quickly. Change out of damp clothing and add warm layers before you become chilled. Higher camps and the summit approach can be below freezing, so suitable sleeping equipment, insulated clothing, gloves, and a warm hat matter.
ADJUST YOUR LAYERS
Wear layers you can add or remove easily. Adjust them before you become too hot or too cold, and keep your waterproof shell within reach. Your main bag may travel separately with the porters, so carry the clothing you could need during the day.
There is no single temperature for the whole climb: conditions depend on altitude, season, time of day, and weather. Check your itinerary and packing guidance before travelling.
YOUR DAYPACK & YOUR MAIN BAG
You carry a daypack while walking, while your main bag travels separately with the porters. Pack your daypack with the items you may need before reaching the next camp, and keep your overnight belongings in your main bag. Confirm baggage limits and equipment arrangements with your operator before travelling.
YOUR DAYPACK — WITH YOU
Keep the things you need during the walking day within reach:
- Drinking water and personal snacks.
- Waterproof jacket and trousers.
- Extra warm layers, gloves, and a warm hat.
- Sun hat, sunglasses, and sunscreen.
- Personal medicines and essential toiletries.
- Phone or camera, protected from rain.
- Headlamp, especially for early starts or late arrivals.
Pack small items in waterproof pouches or a suitable bag liner. Check your daypack before leaving camp; your main bag may be unavailable until the next overnight stop.
YOUR MAIN BAG — WITH THE PORTERS
Pack the belongings you need at camp and overnight:
- Spare trekking clothes and underwear.
- Warm evening clothing and spare socks.
- Sleeping bag, where required by your equipment arrangements.
- Toiletries and personal washing supplies.
- Camp footwear and other overnight essentials.
Use the bag type requested by your operator and protect its contents from moisture. Confirm the permitted weight, whether sleeping equipment counts towards it, and which equipment is supplied or rented. Keep valuables and anything needed during the day with you.
WHO DOES WHAT ON THE MOUNTAIN?
Your mountain crew has different responsibilities throughout the trek. Guides lead the walking day, cooks prepare meals, and porters transport assigned equipment and supplies between camps. Understanding their roles helps you know what to expect and whom to ask when you need help.
YOUR GUIDES
Your guides lead the group, explain the route, and coordinate the walking day. Ask them about the terrain, pace, and daily arrangements. Tell your guide promptly if you feel unwell or are struggling, rather than waiting until you reach camp.
YOUR COOKS
The cooking team prepares meals within the practical limits of mountain kitchens and supplies. Discuss dietary requirements and allergies before booking so the company can confirm what it can accommodate. Meal plans and dining arrangements depend on your package.
YOUR PORTERS
Porters carry assigned luggage, equipment, and supplies between overnight stops. Their loads and responsibilities differ, so you may see them travelling separately from your walking group. Keep the trail clear when they pass, and carry your own daytime essentials.
Before booking, ask how the company supports its crew, including porter load limits, suitable equipment, meals, accommodation, and tipping arrangements.
PHONES, CHARGING & PHOTOGRAPHY
Plan to use your devices without dependable mobile reception or charging facilities. Download useful information before departure, protect your electronics from the weather, and let family or friends know that you may be out of contact during the climb.
MOBILE SIGNAL & STAYING IN TOUCH
Reception can vary along the route. Do not depend on being able to make calls, send messages, or access the internet whenever you want. Download booking details and other useful information before departure. Agree with people at home that a delayed reply does not automatically mean something is wrong.
BATTERIES & CHARGING
Bring a suitable power bank and the correct charging cables, and confirm any charging facilities with your operator. Cold conditions can reduce battery performance, so keep devices and spare batteries protected according to the manufacturer’s guidance. Use battery-saving settings and avoid unnecessary screen time.
TAKING PHOTOS CONSIDERATELY
Keep your phone or camera accessible and protected from rain and dust. Stop somewhere secure before taking photographs, and avoid blocking narrow paths or delaying the group. Ask permission before photographing crew members or other climbers. Tell your guide if you need a brief photo stop.

PRACTICAL QUESTIONS, ANSWERED
LIFE ON KILIMANJARO: YOUR QUESTIONS
How many hours will I walk each day?
Walking hours vary by route, itinerary stage, terrain, weather, and group pace. Check the daily estimates in your proposed itinerary rather than assuming every day will be similar. The summit stage usually involves a much longer period of walking, including the descent.
Can I access my main bag during the trek?
Your main bag normally travels separately with the porters, so do not expect access during the walking day. Carry water, snacks, weather protection, personal medicines, and other daytime essentials in your daypack.
What can I do during free time at camp?
You may have time to rest, organise your equipment, read, or talk with other climbers. Some afternoons include an acclimatisation walk or other scheduled activities. Check your guide’s briefing before making plans or leaving camp.
Will I be able to shower or wash my clothes?
Do not plan around having showers or laundry facilities during the trek. Washing arrangements depend on the route and package, so confirm what is provided before travelling. Bring appropriate personal hygiene supplies and enough clothing to manage without regular laundry.
What should I do if I cannot keep up with the group?
Tell your guide early if the pace feels difficult or you need a break. Explain how you feel so they can assess the situation and advise you. Avoid trying to hide difficulties or continuing alone without discussing it with your guide.
