The more days you spend out on the mountain, the more your trip will cost. But choosing the shortest and therefore cheapest trip is not advisable. Most people who do not make it to the summit fail because of altitude sickness. The more time spent in acclimatizing to the altitude, the better chance you have of reaching the top. In our experience, those who choose less expensive trips which are only five or six days in length are far more likely to suffer altitude sickness and far less likely to succeed. Seven-day or longer trips are what we strongly recommend. On trips of this length, climbers have more time to acclimatize, and their bodies adapt better.
You will note from our website that most of our trips are seven-days at least. Remember that one of those days is for descent. This length of trip is ideal, in our opinion, for beginners and also for those with some experience of climbing. Experienced climbers who have already become acclimatized to altitude before tackling Kilimanjaro – maybe by tackling Mount Meru first – might choose a six-day climb, but we cannot recommend them for other climbers. (Note that Mount Meru is the next-highest Tanzanian peak, standing at 4566 metres). A seven-day Kilimanjaro trip gives climbers enough recovery time once they reach the end-of-day camp, and this recovery time is vital for climbing at altitude.
Some climbers even choose an eight-day climb, giving them even more time to adjust to the altitude and allowing a more relaxed pace at which to tackle Kilimanjaro
