A long trip to a country in Africa (6)
I believe the answer is:
angola
'country in africa' is the definition.
(African nation)
'a long trip to a' is the wordplay.
'trip' indicates anagramming the letters.
'to' is a charade indicator (letters next to each other).
'long' with letters rearranged gives 'ngol'.
'a'+'ngol'+'a'='ANGOLA'
(Other definitions for angola that I've seen before include "South-west African country, capital Luanda" , "It's no gala in this African country" , "Country of south-western Africa" , "SW African nation" , "African country, former Portuguese colony" .)
