It is also recommended to take the camera with dust-proof bags, camcorder, binoculars, torch for finding your way in the lodges/camps at night. Stock up with replacement batteries for all the above goods.

Even if you have taken anti-malaria tablets, please carry some insect repellent. A spare pair of spectacles or contact lenses is also a good idea.
And a good deal of patience and a sense of humour – for this is AFRICA!
