Rhino tracking offers thrills to bush detective and adrenalin junkie alike. With the huge but placid white rhino, this is not too hard. The smaller, shyer and stroppier black rhino is more of a challenge. Imfolozi Game Reserve, in South Africa’s KwaZulu-Natal, is Africa’s rhino capital. Mkhaya Game Reserve in nearby Swaziland also offers excellent tracking of both species. Imagine Africa (020-7622 5114; imagineafrica.co.uk) has a six-night self-drive South Africa/Swaziland package, including the three-night Imfolozi Wilderness Trail and two nights at Mkhaya, Swaziland, from £1,569, including car hire and international flights. The same company also offers a one-week self-drive safari to Namibia, including three nights at Desert Rhino Camp in Damaraland and two nights in the Etosha National Park, for £2,600, including international flights and car hire.
