Most parts of the South Africa can be safely visited by travellers, provided they take common sense safety precautions, much as recommended in most countries and big cities.
Here is some good South African safety advice:
Avoid deserted areas at night, stick to busy and well-lit streets.
Don't wear flashy jewellery - in fact leave it at home.
Keep photographic equipment close to you at all times.
Keep car doors locked and windows closed, and carry a map in case you should get lost. Don't leave bags or valuables on the seat next to you - rather lock them in the boot. Park in well lit areas.
Don't leave luggage unattended.
Store valuables in the hotel safe and leave your hotel room door locked at all times, even when you are in it.
Limit the amount of money you carry on your person. Don't accept offers of assistance at ATMs and keep your pin numbers out of the view of others.
When using a credit card in restaurants, ask the waiter to bring a portable credit card machine to your table. Report stolen or lost cards immediately.
If you're in doubt about a place you wish to visit or how to get there, have a word with your hotel concierge first or contact the National Tourism information and Safety Line on 083 123 2345. If you need a taxi, ask the hotel to order one on your behalf from a reliable service.
In rural areas, watch out for wild or farm animals - road signage will warn you when you need to take care.
