The discussion of South African goodies reminded me that there is a wonderful place in Botswana that most mammalwatchers seem to be unaware of: Central Kalahari Game Reserve. It’s a huge area, very remote (you need to be fully self-sufficient), but cheap to visit by Botswanan standards. It’s the best place in Africa to see honey badgers (we saw 15 in 3 days, all in broad daylight) and porcupines (abundant around campgrounds). We also saw two caracals, some interesting rodents, huge herds of gemsbok, and a black-maned lion of truly outstanding size. Everything is very tame there. Wild dogs and brown hyenas are frequently seen, although we missed them (saw tracks of both, but too old to follow). Also good for advanced birding and herping (particularly larks, raptors, bustards and cobras).
A trip there can be combined with a visit to Khama Rhino Sanctuary, where both rhinos are guaranteed (or at least were in 2008) and brown hyenas frequent the campground (we saw one rather easily). Other campground residents include red rock rats and Namaqua rock rats.
