Coastal area (7)
I believe the answer is:
seaside
'coastal area' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for seaside that I've seen before include "By the briny" , "Old song 'I do like to be beside the . . . . . . .'" , "Popular resort area" , "Holiday place" , "Beach location" .)
