Staying Warm on Kilimanjaro: Layering and Camp Tips

Many climbers are surprised by how cold Kilimanjaro gets. You start in warm, humid rainforest, but within a few days nights at camp are often below freezing, and summit night can be bitterly cold.

Staying warm is not about one big jacket. It is about managing layers, moisture and energy throughout the day and night. These are the habits our guides teach every climber.

Master the layering system

Layering lets you adjust to changing conditions quickly. The basic system has three parts: a base layer that moves sweat away from your skin, a mid layer that traps warmth, and an outer layer that blocks wind and rain.

Choose merino wool or synthetic fabrics and avoid cotton, which holds moisture and makes you cold. Add a warm insulated jacket for camp and summit night.

Plan your layers around the zones you will pass through. In the rainforest, a light, breathable shirt and a rain jacket may be all you need. On the moorland and in the alpine desert, add fleece and wind protection. Above high camp, you will likely wear almost everything you brought. Keeping layers easy to reach in your daypack makes changes quick.

Avoid getting sweaty

Sweat is one of the biggest causes of feeling cold later in the day. Start each morning slightly cool, and remove a layer before you begin to overheat rather than after. When you stop for a break, put a layer back on right away to hold in warmth.

Change into dry clothes as soon as you reach camp. Keep one set of dry base layers just for sleeping, and never wear them on the trail.

Sleeping warm at camp

Cold nights can disrupt sleep, and good sleep helps with acclimatization. A few simple tricks make a big difference.

• Eat a warm meal and have a hot drink before bed
• Fill a sturdy water bottle with hot water and put it in your sleeping bag
• Use a sleeping bag liner for an extra layer of warmth
• Wear a hat and dry socks to sleep
• Keep tomorrow's clothes and batteries inside your sleeping bag
• Use the toilet before getting into your sleeping bag

Hands, feet and face

Extremities get cold first. Bring liner gloves plus insulated mittens for summit night, since mittens are warmer than gloves. Pack spare warm socks, and avoid lacing boots too tightly, which reduces circulation.

A buff or balaclava protects your face from wind, and a warm hat makes a big difference. Some climbers bring chemical hand warmers as a backup for summit night.

Keep spare gloves in a waterproof bag in your daypack. If your first pair gets wet from snow or sweat, a dry pair can make the difference between misery and comfort.

Fuel and hydration

Your body generates heat by burning calories, so eat regularly even if altitude reduces your appetite. Warm drinks at camp help both hydration and morale. Dehydration makes you more likely to feel cold, so keep drinking water throughout the day.

Simple snacks such as nuts, chocolate and energy bars are easy to eat on the move and provide quick fuel when the temperature drops.
