Northwest of Mzuzu along the Zambian border lies Vwaza Marsh Game Reserve, a 400 square mile area of marsh and plain. Vegetation in the reserve varies from forest and grassland, to thin woodland and marsh. At the heart of the reserve is Lake Kazuni, home to a large number of hippo which can often be seen basking on sandbanks during the day. The lake attracts large herds of elephant - particularly in the dry season - plus buffalo, waterbuck, eland, roan, sable, zebra, impala and baboons. The bird life, especially waders, is excellent. Predators to be found in the area include lion and leopard whilst wild dog are elusive but occasionally seen. The reserve is undeveloped and has few roads, however walks and drives can be rewarding.
