Kericho is the biggest town in Kericho County located in the highlands west of the Kenyan Rift Valley. Standing on the edge of the Mau Forest, Kericho has a warm and temperate climate making it an ideal location for agriculture and in particular, the large scale cultivation of tea.
The town is strategically located along Kenya's western tourism circuit with access to Lake Victoria, the Maasai Mara National Reserve and Ruma National Park.
As of the 1999 census, the town has a population of 150,000. Kericho is the home town of the Kipsigis, who are a part of the Kalenjin people.
The etymology of Kericho is unclear. One theory has it that it was home to the region's first hospital, built by the colonial British at the start of the 20th Century. This is in reference to kerichek the word for medicine in the Kipsigis language.
Other theories have it that the town was named for a local medicine man called Kipkerich or after a Maasai chief, Ole Kericho who was killed in the 18th Century by the Abagusii.
