Named after the Khoisan word for 'a wet place', the Cango Caves are heavily commercialised but still impressive. There's a choice of tours on offer, although it's fun to choose one of the longer tours which can involve crawling through tight spaces; the claustrophobic or unfit may wish to opt for a gentler excursion.
Addo Elephant National ParkThis national park is near the Zuurberg Range in the Sundays River Valley. There are hundreds of elephants in the park and you'd be unlucky not to see some. They are the remnants of the herds that once roamed the Eastern Cape. Be aware that the park closes if there has been heavy rain, as the dirt roads can become impassable; call ahead if in doubt.
Blyde River Canyon Nature ReserveThe Blyde River Canyon Nature Reserve is one of South Africa's scenic highlights, featuring the awesome viewpoints of Wonder View and God's Window. Once you could park quietly and enjoy the views at the lookouts; now there are entry gates and a battery of souvenir sellers. While most visitors drive, it's worth exploring the impressive rock formations and rainforest on foot if you have time.
Kgalagadi Transfrontier ParkCovering an area about twice the size of Kruger, and described as semi-desert, this park is hauntingly beautiful, with large populations of birds, reptiles, rodents, small mammals and antelopes. Aim to visit in June and July when the days are coolest and the animals have been drawn to the bores along the dry river beds.
Kruger National ParkAs well as being one of the most famous wildlife parks in the world, Kruger National Park is among the biggest and the oldest - it turned 100 in 1998. You can see the 'big five' here (lions, leopards, elephants, buffaloes and rhinos) as well as cheetahs, giraffes, hippos, all sorts of antelope species and smaller animals.
