33. Dar Es Salaam, Tanzania — The largest city in the country is rife with crime. Britain's government says on its foreign travel website: "British tourists have been kidnapped, robbed and forced with the threat of violence to withdraw cash from ATMs and arrange cash transfers up to £5,000 through Western Union after being befriended by strangers or using unlicensed taxis. Walk as far away from the road as possible."
