The Tuli Block is a long, thin fringe of land demarcating Botswana's southeastern border.
Tuli consists mainly of privately owned game farms, offering spectacular safari tourism. The eastern section up to and including Redshield Farm has been declared a game reserve, known as the Northern Tuli Game Reserve. Tuli has a fascinating frontier history and is renowned for its curious geographical features — Solomon's Wall and the Tswapong and Lepokole hills where the ancestors of the San people left traces of their rock paintings.
Tuli reaches from the Northeast corner of Botswana, where the Shashe and the Limpopo Rivers meet, down to the Notwane River north of Olifants Drift in the South West. The entire conservancy area, including the adjacent safari area bordering the Tuli Circle, comprises about 800,000 hectares. The Tuli Block is quite different from anywhere else in Botswana. It is referred to as the Hardveld because of the rocky outcrops and the abundance of stones and pebbles of all shapes and sizes. The red sand of the Tuli area is an unforgettable trait, as well as the massive trees that occur along the banks of the Limpopo.
Much of the area is unfenced allowing the animals to roam freely between the Motloutse and Limpopo rivers. The vegetation is spectacular, the scenery diverse. Gigantic Nyala trees and the yellow barked fever trees grow along the riverbanks. Gaunt sesame trees take root in rocky outcrops. Animals flourish in the wild terrain. Wildebeest, kudu, eland, impala and waterbuck migrate through the area. Lions, leopard and cheetah follow the game and mingle with the large herds of elephants. Bird life proliferates in the diverse environment. Tuli is one of the best places in southern Africa for ornithologists. Over 350 species of birds have been identified in the area, including rock thrushes, boulder chats, shrikes and cormorants. Different kinds of kingfishers dart into the streams and rivers, while waders stand in the shallows.
Solomon's Wall is one of the most fascinating and dramatic geographical features. The sheer basalt cliffs, 30 metres high, once formed a natural dam across the Motloutse river. A huge lake filled up behind it, with a waterfall spilling over the dyke during the rains, leaving rich mineral deposits of quartz, agate and other semi-precious stones. It was in the sands higher up the Motloutse river that the first alluvial diamonds were found in Botswana, giving a hint of the wealth that was to come. The Tuli area is also famous for its Tswapong and Lepokole hills.
