Most of the time you'll be most comfortable in light, summer-weight clothes but do pack a warm jacket, socks, good shoes and a rain jacket. Pack sunscreen � lots of it � and a hat and sunglasses. Make sure you have at least one cool shirt with a collar for sun protection. Stock up on insect repellent and, if you'll be in a malaria area, ensure you have a cool, long-sleeved shirt and cool long pants for evenings. Take good walking shoes.
Always pack a bandanna or cotton scarf and a sarong, kanga, pareo, kikoi � whatever you want to call it. If you're spending time watching game, you should try to wear reasonably neutral colours . You don't need formal clothes, but you will need something pretty smart for exclusive hotels and the Blue Train.
