What do I really need to bring for Kilimanjaro, and what can I rent locally instead of buying it?
What gear do I need for Kilimanjaro, and can I rent it in Tanzania?
Kilimanjaro needs trekking gear for weather from tropical rain to a summit night around minus 10 to minus 20 °C, but no technical climbing equipment: no rope, crampons, harness or ice axe on any of the normal routes. The Kilimanjaro gear list has every item with a box to tick, so you can mark what you already own and see what is left to buy or rent.
