Hunting trip mostly free of risk and very dry (6)
I believe the answer is:
safari
'hunting trip' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for safari that I've seen before include "African wildlife trip" , "A journey to see or hunt wild animals" , "tropical trip" , "Expedition to look at wildlife" , "Overland journey to look for wild animals" .)
