Sunglasses, sun hat, sun cream, a small torch, and a pair of binoculars are part of essential safari packing.
Also, bring your favorite book for the hammock. If you enjoy reading in bed, it might be smart to bring your head torch – it gets a bit dark in Africa during nighttime. Soft bags are easier to store in safari vehicles or small airplanes than solid suitcases. Note that if you are flying to the Mara, the weight limit is 15kg per person.
