 Crocodiles frequent the river below, and vervet monkeys sometimes terrorise patrons in order to steal their food.13 km south of Skukuza in the Rhenosterkop region of the park is the Stevenson-Hamilton memorial, on a rock formation called Shrimantanga.The area is one of the few unstaffed areas where one is allowed to leave a vehicle (at one's own risk), but is in an area known for leopards.
