Kilimanjaro is climbable all year round. The best months to climb are December-March, and September-October, which are the warmest and driest months. The next best are June to August, but they are colder. July, August, and September are the busiest months. Summiting on or soon after a full moon is very beautiful and helps illuminate the landscape without using headlamps. However, it is also very bright for sleeping and stars are not as visible. 

Malaria is a serious problem in East Africa so you must consult your doctor about getting effective malaria prophylaxis for your visit. Many people are avoiding Lariam nowadays and using Malarone. You cannot catch malaria above 3000 metres on Kilimanjaro, but you must be careful below that altitude, particularly if you visit the coast where the strains of malaria tend to be especially virulent. 

Temperatures range from 25 to 30 degrees Celsius at the foot of the mountain and -15 to -20 degrees Celsius on top plus wind chill. Lower down, it can be wet and humid, but higher up, there can be snow. Rain and snow may be encountered any time of the year! 

It requires no technical climbing experience, and any moderately fit person can summit the mountain. 

Your decision will depend on where you want to sleep and the hiking distance each day and number of days of each route. On the Marangu Route, you sleep in huts with simple beds, while on all the other routes, you sleep in tents. There are two main routes on the mountain: the Marangu and Machame. You may also want to consider the Rongai Route as it is far less traveled. The Lemosho Route is a good choice if you want a longer route (8+ days). Kindly visit our Kili Routes page. 

There has been a lot of negative press about Marangu. In our view, and we arrange treks on all the routes, it is very unfair. This is the only route that uses huts rather than tents and some years ago there was a serious problem with overcrowding in the huts. In those years the Machame route was much less frequented. But we think the main reason that some operators speak against the Marangu and boost the Machame is that the booking system for Marangu is demanding of operators' time. There is no booking system for Machame (nor the other camping routes). You just show up at the Machame gate the first morning of the trek. No one ever knows how many people will be on the trail until the gate closes for that day. There is a daily quota of only about 70 climbers allowed to start on the Marangu route on any day (this is why booking is not always easy).

There are many days in the season when there are many more climbers on the Machame route than on the Marangu. This is not in any way to denigrate the very beautiful Machame route. But these are things to bear in mind when hearing the Marangu route described as the tourist, easy or Coca Cola route and the Machame as the scenic or the whisky route! It is true that you will hear many people who have climbed Machame say that it is better than Marangu, and this is conveyed to many of the guide book writers. But remember that the overwhelming majority of climbers only ever climb one route. The chances are that the climbers who say this have never been on the Marangu route and are simply repeating what they have been told or have read.
