Spruce overlooking lakes, timeless, charming scene (5)
I believe the answer is:
idyll
'charming scene' is the definition.
(I've seen this before)
'spruce overlooking lakes timeless' is the wordplay.
I cannot really see how this works, but
'lakes' could be 'll' (a geographical abbreviation for lake written twice) and 'll' is located in the answer.
This explanation may well be incorrect...
(Other definitions for idyll that I've seen before include "very happy situation" , "Happy peaceful scene" , "Charming life in the country" , "Romantic pastoral composition" , "Simple story" .)
