Tanzania is the biggest (land area) among the East African countries of Gapco's operations (i.e. Kenya, Uganda and Tanzania). Tanzania has a spectacular landscape of mainly three physiographic regions namely the Islands and the coastal plains to the east; the inland saucer-shaped plateau; and the highlands. The country has the largest concentration of wild animals. It also has pristine sandy beaches and Africa's highest and snow-capped mountain, Mt. Kilimanjaro.

Dar es Salaam is the commercial capital and major sea port for Tanzania mainland and it serves as a gateway to the neighbouring land-locked countries of Malawi, Zambia, Burundi, Rwanda and Uganda, as well as Eastern DRC. Other sea ports include Zanzibar, Tanga and Mtwara.
