Do I really need to carry my own water?

Yes, you are responsible for carrying 3 liters of water per day in your daypack, as the porters will not be near you on the trail during the hike.

Can I leave my extra luggage at the hotel?

Yes, most reputable Kilimanjaro trekking companies provide secure storage at their base hotel for any gear you don't need on the mountain.

How to Pack for Climbing Mount Kilimanjaro

You need a strict layering system to handle temperature swings from 30°C in the rainforest to -15°C at the summit. Pack your gear into two bags: a 70-90L duffel for the porters and a 30-35L daypack for the items you carry yourself.

Master the layering system. Bring a moisture-wicking base layer, a fleece or down mid-layer for insulation, and a high-quality waterproof shell jacket and pants. Avoid cotton entirely as it holds moisture and will make you cold.
Choose the right boots. Bring waterproof, broken-in trekking boots with good ankle support. Do not buy new boots right before the trip; walk at least 50km in them beforehand to prevent blisters.
Organize with dry bags. Porters will carry your main duffel in a tarp-covered bag, but it isn't 100% waterproof. Use internal dry bags or heavy-duty trash bags to wrap your clothing so you have a dry set of clothes every night.
Prepare your daypack essentials. Your daypack must contain 3L of water, high-energy snacks, sun protection (hat and SPF 50), an extra thermal layer, a rain cover, and your camera.
