The British Foreign and Commonwealth Office advise against all but essential travel to parts of the north western Copperbelt, Central and Luapula provinces, which are close to the border with the Democratic Republic of Congo (DRC), particularly after dark. There are continuing reports of armed cross-border raids from the DRC. You should also be aware of landmines in this area, and on the borders with Angola and Mozambique.
The threat from terrorism is low. But you should be aware of the global risk of indiscriminate terrorist attacks which could be against civilian targets, including places frequented by foreigners.
Around 100,000 British tourists visit Zambia every year and most visits are trouble free, although armed robberies and car hijackings are on the increase. The main types of incident for which British nationals require consular assistance in Zambia are for stolen passports and drug and immigration offences.
We strongly recommend that you obtain comprehensive travel and medical insurance before travelling. You should check any exclusions, and that your policy covers you for the activities you want to undertake.
