There are 2 main reserves in Zambia, both with vast plains and few visitors, so they have a wild and unexplored feel. South Luangwa with lakes and rivers is famed for walking safaris, hIgh density of leopard, and endemic Thornicroft's giraffe and Crawshay's zebra. Kafue has even fewer camps and is closer to Vic Falls. This is serious safari country - don't expect pools, a/c etc; camps are intimate, low impact and close to nature. Zambia.
Best time: May to October when it's dry - but October can be very hot - most camps close during the wet season.
Access: Charter from Victoria Falls or Livingstone (1-2 hrs) to Kafue; the closest city to South Luangwa is Lilongwe (1hr flight or 5 hr drive)
