angola is one of the choice countrys to go to in west africa. same rules apply there as for anywhere else in the region. remember your visa, vaccination cards (specially yellow fever) and $$$$$’s
talk to your doc about malaria pills not near as bad offshore but if your onshore for a while you will need it. and a good mozzy spray
going out drinking? stay in a group otherwise the hotels are good enough.
