Locate winds around opening to meadow, idyllic place (7)
I believe the answer is:
camelot
'idyllic place' is the definition.
(mythical court of King Arthur)
'locate winds around opening to meadow' is the wordplay.
'winds' indicates anagramming the letters (the letters wind around).
'around' means one lot of letters goes inside another.
'opening to' says to take the initial letters.
The first letter of 'meadow' is 'm'.
'locate' with letters rearranged gives 'caelot'.
'caelot' placed around 'm' is 'CAMELOT'.
(Other definitions for camelot that I've seen before include "Place where King Arthur held court" , "King Arthur's kingdom - or JFK's" , "Idyllic place" , "romantic place" , "King Arthur's town" .)
