Voi is the main town of the southern area of Kenya, with a developing industrial and commercial center. It is situated on the main Nairobi/ Mombasa road, and is the junction for the road heading to the Tanzanian border at Tavata. It was in the first rail head when the line was under construction, and is still a major station. The Tsavo East National Park borders almost on the town, and to the west you find vast sisal estates, leading into the Taita Hills.
