According to Wikipedia, The Aberdare Range (formerly the Sattima Range, Nyandarua) is a 160 km long mountain range of upland, north of Kenya’s capital Nairobi with an average elevation of 3,500 metres (11,480 ft). It is located in Nyandarua County, west central Kenya, northeast of Naivasha and Gilgil and just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua means a drying hide due to the distinctive fold of its silhouette.
The Aberdare Range forms a section of the eastern rim of the Great Rift Valley running roughly north to south. On the west, the range falls off steeply into the Kinangop Plateau and then into the Great Rift Valley. On the east, the range slopes more gently. Lake Naivasha and the distant Mau Escarpment can be seen from peaks in the range.
The Aberdares are the water catchment area for the Sasumua dam and the Ndakaini dam which provide most of the water for Nairobi. The mountain forests are catchment areas for the Tana River, the largest river in Kenya, supplying water to the Seven Forks hydroelectric power complex which generates over 55 percent of Kenya’s total electricity output.
Mount Satima, also known as Mount Lesatima and often abbreviated to Satima or Lesatima, is the third-highest mountain in Kenya and the highest in the Aberdare Range. The Maasai name is Oldoinyo Lesatima, which has a variety of alternative spellings, such as Ol Donyo Le Satima, and means “mountain of the bull calf”.
The terrain is moderately favourable through the moorland to the peak. Rock formations are a spectacle along the route as well as small animals. The views from the top is exceptional, especially on a clear bright day. It’s a hike that will relax and rejuvenate the mind to peacefully forget the daily hustles and indulge in the calmness of the soul
