Though rumours of the existence of the lake had previously reached the east coast, Tanganyika was not visited by any European until, in 1858, the famous expedition of Burton and Speke reached the Arab settlement of Ujiji and partially explored the northern portion.
North of Tanganyika the valley is suddenly interrupted by a line of ancient eruptive ridges, which dam back the waters of Lake Kivu, but have been recently cut through by the outlet of that lake, the Rusizi, which enters Tanganyika by several mouths at its northern end.
Caravans from Dar-es-Salaam to Tanganyika take 60 days to do the journey.

To the north-west end of Lake Kivu, thence across that lake near its western shore, and along the river Rusizi, which issues from it, to the spot where the Rusizi enters the north end of Lake Tanganyika; along the middle line of Tanganyika to near its southern end, when it is deflected eastward to the point where the river Kalambo enters the lake (thus leaving the southern end of Tanganyika to Great Britain).

Into Tanganyika flows the Malagarasi, a considerable river with many affluents, draining the west-central part of the plateau.
