I hired a car at J'burg airport and headed up to Kruger for a week self-driving around. A 2WD road car is fine even on the gravel tracks. Booking accommodation before going is recommended on the SAN web site.
I stayed at three different 'camps' from the south to the north to view a range of habitats. Self-driving gives you much more freedom to take photos (I recommend turning off the engine, taking a beanbag and 300mm+ lens to get sharp shots). The 'camp sites' offer guided bush walks which I highly recommend.
Four-hour drive from Johannesberg airport to the nearest entry gate.
