Direct buses run from Entebbe and Nairobi through Arusha to Dar es Salaam. There are also buses from Mombasa to Dar es Salaam and from Voi to Moshi. Visitors who prefer to fly in or out through Nairobi can use the Impala Shuttle bus between Nairobi and Arusha. Overland travel from Ruanda is by local buses and minibuses. There are also buses crossing the border from Malawi. Any overland travel from Burundi should not be attempted.

From Mozambique Tanzania can be reached from the town Quionga from where there are minibuses (or similar) to a simple ferry at the mouth of the river Ruvuma. Once on the Tanzanian side, the travel continues to Mtwara, if some kind of transport can be found and if the road on the river floodplain is negotiable.

There are passenger trains from Kapiri Mposhi in Zambia to Dar es Salaam. Indeed, once a year an old-style train leaves from Cape Town to appear in Dar es Salaam 13 days later. The price is forbidding for most of us.

There are also passenger ships on Lake Nyassa from Malawi to Itungi Port and on Lake Tanganyika from Zambia and Burundi to Kigoma. There is conflicting information on whether there is or is not at present any vessel between Uganda and Mwanza.
