2. The Drakensberg

Julia moves to the interior for her second walk and the grandest mountain range in southern Africa, the Drakensberg. The 3,000m Cathedral Peak is the ambition for Julia and her Zulu guide Zee. As she quickly discovers, even the fittest and most experienced walkers need luck on their side when it comes to the dramatic weather of these mountains. With Zulus, Brits and Boers to provide the history, this is an outing filled with drama and fascination set against a backdrop sometimes described as the most beautiful on earth.

3. The Kruger

Having progressed from South African coast to mountains, Julia ups the ante as she prepares to head out on foot in one of the world's most famous game reserves. Call it exhilarating or foolhardy, this is a walking adventure amongst the biggest and most dangerous beasts in Africa. But Julia is well looked after by Jaco, an expert game ranger who proves that the Kruger is far more than just big cats and elephants. This is a unique opportunity to roam freely in one of the world's true wildernesses.

4. The Green Kalahari

Julia's final walk takes her to the remote north-west corner of South Africa. This is the edge of the Kalahari Desert and the setting for Julia's most adventurous undertaking yet. Far away from the major tourist draws of the country, it is an insight into a true African world. Set against the stunning red geology of Augrabies National Park, it's a stark but beautiful walk, encountering simple rural lives and remarkable agriculture, utterly reliant on the broad waters of the Orange River.
