Pilanesberg National Park

This guide to Pilanesberg National Park near Johannesburg opens with a mystery from the early 1990s: rangers kept finding dead rhinos with no bullets and no missing horns, only deep puncture wounds. It traces the reserve back to 1979's Operation Genesis, when some six thousand animals of twenty-two species were trucked into this extinct volcano's crater, among them young elephants orphaned by culls in Kruger National Park. A listening tip: the ring of hills around you are the eroded walls of that same ancient volcano.
