Isiolo is a town in the former Eastern Province, Kenya. It is situated in the Upper Eastern sub-region, and lies 285 kilometres north of Nairobi, the capital city of Kenya. The town grew around the local military camps, much of the population being descended from former Somali soldiers who had fought in World War I as well as other Cushitic-speaking pastoral communities and the Ameru community. The town has an estimated population of 80,000 people, most of them living in the rural outbacks of the District. There is an increasing urban population in the recent years, especially from as far as Moyale, Marsabit and Mandera. The Isiolo town is also becoming a centre of interest because of its newly acquired status as a resort city cashing in on the popular Samburu and Shaba Game reserves, which have become preferred destinations after the famed Maasai Mara. Isiolo lies along the long A2 Road, leading towards Marsabit and Moyale much farther north. The town is served by Isiolo Airport, which is set to be upgraded to an International Airport to serve tourism and local exports.
