The Kilimanjaro Trek(s) takes around 7-10 days to hike it and leads up to the summit of the highest mountain of Africa: The Volcano Kilimanjaro in Tanzania. There are a few different trails and around 20.000 people each year do the hike to the top of Kilimanjaro
The Kilimanjaro trek is considered a challenging hike to one of the highest mountains on Earth. And it is the African mountain challenge on the “Seven Summit challenge” to climb the highest mountain on each continent on Earth.
The thin air and the cold temperature on the top, almost 6000m. / 20.000 ft above sea-level is a large part of the challenge climbing Kilimanjaro.
Most people dying on Kilimanjaro lose their life due to altitude related diseases and only a bit more than 60% of those attempting to reach the summit of Kilimanjaro reach it.
Some adventurers with an even more challenging starting point has succeeded in climbing Kilimanjaro, including Bern Gosen in wheel chair (Bern Gosen in six days 2007 ) and Kyle Maynard without legs or hands ( Kyle Maynard unassisted 2012)
