The weather at the highest elevations is often cold and wet.
Fauna
The mountains are rich in wildlife, including animals who migrate to higher altitudes during the hot season in the surrounding savanna. The mountains are home to a number of endemic bird species such as Hinde's babbler which lives only on Mount Kenya.
The lower elevations of the mountains have been extensively used for forestry and for growing tea and coffee and much of the original forest has been lost, including the cloud forest that once covered much of Kilimanjaro. Climbing these mountains is a major attraction and Kilimanjaro National Park attracts hundreds of visitors each year, many of whom access the mountain from the coffee-growing town of Moshi.
Exploration
The mountains were discovered by Europeans in order of distance from the coast, which also happens to be in decreasing order of height. They were also explored and climbed in this order.[1]
