An increasing number of airlines are flying to Kenya, and Nairobi's Jomo Kenyatta International Airport has become a hub for East and Central Africa. National carrier and biggest airline in the country is Kenya Airways, which among others also provides direct flights from Nairobi to several West African countries, e.g., Lagos in Nigeria, Bamako in Mali, as well as direct flights to Bangkok and connections to Hong Kong and China. A recent code-share agreement with Korean Airlines has also brought the Korean peninsula within reach.
By ship
This is limited to Lake Victoria e.g., Mwanza in Tanzania to Kisumu in Kenya and the coastal area e.g., Mombasa-Zanzibar cruises.
By train
Train services link only Kenya's major cities. There is no passenger train service linking Kenya with neighboring countries, though there are cargo lines.
By car
The roads may be poor, but all neighboring countries can be accessed including Ethiopia via the border town of Moyale, Uganda via Busia or Malaba, and Tanzania via Namanga.
Beware of overland routes coming through the northern deserts as these are essentially lawless regions. Most vehicles traveling through the area travel via armed convoy.
