Deep within the shadows of the dense valley bushveld of the Sundays River region of the Eastern Cape lies the Addo Elephant National Park.

Here, the evenings are punctuated by the strident howl of the black-backed jackal, and the francolin's call heralds each new dawn. Safe from relentless persecution in the past, the grey leviathans of the bush now roam in peace.

The original Elephant section of the park was proclaimed in 1931, when only eleven elephants remained in the area - today this finely tuned ecosystem is sanctuary to over 450 elephants, Cape buffalo, lion, black rhino, a variety of antelope species, as well as the unique flightless dung beetle, found almost exclusively in Addo and their Addo has only just begun.

With plans to expand the  164 000 ha Addo National Elephant Park into a 360 000 ha mega-park. In addition, plans include the proposed proclamation of a 120 000 ha (296 500 acre) marine reserve that includes islands that are home to the world's largest breeding populations of Cape gannets and second largest breeding population of African penguins.
