Covering 45,000km² of wilderness, with grassy plains, open woodland, mountains and forests, the Selous Game Reserve (pronounced 'seloo', and named after the great explorer and hunter, Frederick Courtney Selous) is Africa's largest game reserve. It's about three times the size of South Africa's Kruger National Park, and twice the size of the Serengeti National Park. In a fitting tribute, it is also one of Tanzania's three World Heritage Sites.
