A fir, we may deduce, in recreational area (10)
I believe the answer is:
fairground
'area' is the definition.
(fairground is a kind of area)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fairground that I've seen before include "that holds attractions" , "Scary ride here perhaps" , "good enough for entertainment" , "Entertainment centre" , "rides here" .)
