My cousin and I stayed overnight in their tent camp, which is accessed from a different entrance than the main tour route. Animals roam freely over the massive 1800 acre grounds, so they come and go from this area to the tour route. An electric wire surrounds camp to prevent hoofstock from approaching campers.
On way back to camp after dinner in town, we saw these addax grazing outside the main lodge (which is about half a mile up road from tent camp).
