Similarly to Kenya, Tanzania or South Africa, Botswana has over time become a global tourism destination for safari trips.
As far as clothes are concerned, you'll need to pack for summer in order to withstand the hot weather. Avoid bright colours and go for darker tones so that animals won't spot you so easily and you'll be able to better observe them. Unfortunately once evening comes, you won't escape the mosquitoes. So make sure you pack outfits which will protect your arms and legs from their persistent attacks.
Pay the utmost attention to ensure you pack your first aid kit properly. Don't forget, of course, to pack basic medicines to deal with everyday issues. Add medicines to ease indigestion, which Westerners often succumb to, as well as anti-malaria tablets – you'll need to acquire a prescription for these from your doctor.
On safari, you'll quickly realise that you're going to take an incredible number of photos. It's impossible to resist in front of a family of lions or a baby elephant. Make sure you bring a camera, along with enough storage space to save all these incredible moments. A pair of binoculars would also be very useful for spotting more easily the animals who keep their distance. On the administrative side of things, it's always handy to keep a photocopy of your passport with you. This will help you along the way if you lose your original. An international driver's license is a must if you're planning to hire a car. Rather than using traveller's cheques, bring along your debit card for cash withdrawals.
In Botswana, you'll see incredible and breathtaking scenery, so upon arrival make sure you're ready to be stunned!
