From Durban, i suggest you go north, towards Eshowe, where you can visit the Dlinza forest. Then continue north to visit Shakaland, then on to st Lucia where you can stay at Kingfisher Lodge which borders the natural forest. Take the cruise up the estuary (Advantage tours) then take a night game drive with Sharker Barker tours. The guide is absolutley delightful. Visit the cat sanctuary at Emdoneni, and then on to Hluhluwe Imfolosi Game Reserve. Stay at Hilltop camp. This is by far the better side of Durban with lovely beaches and wildlife. If you fancy some snorkeling, go a little further up to Sodwana Bay.
