Working our way back to Cape Town we were never going to take the direct route. There was no way we could resist a little detour into the central plains of Botswana.

The featureless salt pans had an austere beauty but we were happier sticking to the roads between occasional islands of rock. At Khubu Island we learned a little about African civilisations forgotten by history.

Mostly, though, we savoured our time camping beneath marvellous baobab trees.
