The historic MV Liemba is the oldest functioning ferry in the world, and a voyage down Tanzania’s Lake Tanganyika on this landmark is a colorful experience. Your fellow passengers will include traders loading and unloading cargo (anything from pineapples to flip-flops) and locals using the ferry for transport. On the southbound journey, the boat departs from the town of Kigoma and travels 300 miles to Zambia, where its makes its first port of call on land. But in between those two stops, while still on the water, travelers can transfer to smaller ships in order to reach places like Lagosa (a jumping-off point for the Mahale Mountains National Park) or the peaceful beach area of Kipili.
