Having tackled treks across Europe, Julia Bradbury now embarks on a truly grand adventure… in South Africa. Julia sets out on four very different journeys that explore South Africa’s claim to be ‘a world in one country’.

This is a rare chance to go far beyond the 'Rainbow Nation' usual tourist destinations, taking us instead to increasingly remote – and beautiful – locations. But these are all walks that any reasonably adventurous traveller could embark on, and the series offers a fresh and very personal perspective on a gorgeous and fascinating country.
