Who can climb Mount Kilimanjaro? The answer is simple. People of all ages and all levels of experience can make it. Even children and grandparents do it! 
Fitness and training 

You don't need to be super fit to climb Kilimanjaro. Climbing Kilimanjaro means a lot of slow walking, all the way. However, it definitely does not mean you need no training at all! Some recommendations for training are: hiking or longer walks in the nature and mountains within your reach, walking in the hilly areas for 6-8 hours per day and repeating it the next day, wearing the boots you will be wearing on the climb. You should also speak with your doctor before deciding to climb, especially if you have any health problems. 

Altitude and acclimatization 
No matter how much climbing you’ve done, you have to respect a mountain that is over 5000m high! Sufficient fitness is no guarantee that you will reach the top because of high altitude sickness, which is affecting all climbers going above 3000m. Proper and good acclimatization is very important. Our strategy is longer routes and enough time for acclimatization. Coupled with years of mountain guide experience, it ensures that 99% of our customers reach the summit. Unlimited clean water during the climb, trained guides who can easily sport the signs of altitude sickness and quality fresh food provided, mitigate the altitude symptoms to the lowest possible levels. 

Mountain safety 
They are dangers involved in climbing high mountains like Kilimanjaro. It is important to have insurance to cover these risks in case of an accident or medical problems.  

Our guides, porters and cooks are professional and trained to the highest standards, ensuring safe and enjoyable mountain experience. They are all fluent in both English and Swahili. Many of our guides climbed Kilimanjaro more than 100 and some of them over 200 times. For additional level of safety, one guide is assigned to every two trekkers. 

Visa and vaccination 
For travelling to Tanzania, you need a passport which is valid for at least 6 months prior to expiration. Tourist visa usually costs $50 (for US citizens $100) and is valid for three months. Visa can be obtained at the airport on arrival but it is recommended for travelers to obtain their visas in advance to avoid queues and waiting at the airport. It is also now possible to apply for your Tanzania visa online. We urge you to double check the visa and passport requirements for your trip, consult with an embassy or consulate, or use a reputable visa agency. 

It is recommended to get hepatitis A and B, typhoid, influenza, T-dap, chickenpox, shingles, MMR, rabies, yellow fever, meningitis, and cholera vaccinations for Tanzania. The yellow fever vaccination may be optional in some cases. 
Equipment and gear 

The most common mistake that climbers make is that they over pack. Be selective in what you take with you because the porters are limited to carrying 16 kg of your personal belongings. You will need to carry your own daypack. At the summit point, the night time temperatures can range between 7 to -29 degrees Celsius.
