Visa extensions can be made at the immigration office in Bunjumbura. International airlines servicing Burundi are Aeroflot, Air Burundi, Air France, Air Rwanda, Air Tanzania, Cameroon Air, Ethiopian Airlines, Kenya Airways and Sabena. There are also two possible routes between Burundi and the Democratic Republic of Congo although the one passing through the north-western parts of the country via Bugarama could be dangerous. Two routes are available and both use lake Tanganyika at different points. A direct route is to and from Kigoma while the other, perhaps a more interesting route, is via Nyanza Lake and Gombe Stream National Park .
Services connecting Tanzania with Burundi and Zambia are available.
Air Burundi, the national airline does not have regular internal flights. They are not overcrowded and thery are cheaper than taking a taxi. Burundi does not seem to exude obvious travel highlights and many travellers simply pass on their way to other destinations. There is a good beach lined up with hotels and restaurants in the nothern end of Lake Tanganyika between Bujumbura and the Burundi-Zaire border. The postal service is reasonably efficient and international telephone calls can also be made at designated centres.
