The easiest
way to travel to Juba, the Capital city of South Sudan from Nairobi, the
capital city of Kenya, by road is to pass through Kampala, the capital city of
Uganda.
There are
many buses plying the Nairobi-Kampala route. Most can be found along River Road
or around there. Mash Poa, Simba Coach, Modern Coast, Trinity coach, Buscar,
Crown bus, Mombasa Raha, Spanish Coach, La Face, just to mention but a few.
