Venice beach area (4)
I believe the answer is:
lido
'venice beach area' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lido that I've seen before include "Outdoor swimming pool" , "Idol (anag.)" , "Venice's beach island facing the Adriatic" , "Bathing pool" , "Swimming and leisure area" .)
