Luggage:
Choose a duffel bag or soft-sided bag. Ideally, the fabric should be hardy and waterproof and the bag should be lockable. These are ideal for packing into the vehicle, hard suitcases can be often difficult to fit into the vehicles.
Put anything that is of any value in a separate day pack such as a backpack. Anything of real sentimental or monetary value should ideally be left at home.
Clothes:
Pack for hot days and cool nights. Tanzania can be hot and dusty by day but it is often cool and crisp by night. Layers are ideal for safari days. Pack clothing that is able to keep you cool but protect you from the sun and biting insects. Choose mid-tone colours and avoid white or bright colours that may distract the animals and dark colours like black and blue as these can attract tsetse flies.
The best colours are the safari classics: olive, green and khaki. For evenings at lodges you can stay in your casual gear as even the luxury lodges do not expect smart wear out in the bush. Check the temperature before you travel to make sure you have clothing that is warm enough for the season. It is always a good idea to bring a waterproof coat, whatever the season.
Shoes:
As you want to be careful not to over pack, you need to think carefully about what shoes to take. As long as you are not going on a safari that requires a lot of walking, you will be fine with some light hiking boots and some sports sandals (sandals are also great for walking around the camp at night). You may also like to take flip flops for the showers
