Tourists usually book fully organized climbing tours. Porters carry all gear, supplies and luggage on Kilimanjaro, while you only need to carry what you need during the day. Your daypack will usually not weigh more than 5 to 8kg.
It is also possible to hire an additional personal porter to carry your daypack. Climbers with back issues might want to do so.
There is also the option to climb only with a guide and carry all your own gear and supplies. Only the strongest climbers with experience trekking in high altitudes should make use of this option.
