Distances in Tanzania are vast and travel by road can be wearing. Plan to spend more time in fewer parks, you’ll see more and won’t return home exhausted.
Keep your distance from animals and be quiet to avoid distressing the wildlife, follow instruction of ranger or guides, don’t leave your vehicle in the park expert in designated places, keep to recognized tracks to avoid damaging vegetation.
Bring film (especially slide film) and batteries for your camera with you, protect your cameras from dust and keep equipment and film cool.
It is courteous to ask permission before photographing local people, if you intend to take a lot of people pictures be sure to bring an instant camera with you so that you can leave a picture with people you photograph.
