Places to scuba (5)
I believe the answer is:
reefs
'places to scuba' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for reefs that I've seen before include "Groups of submerged rock" , "coral banks" , "Submerged ridges of rock or coral near the surface of water" , "Ridges of rock or sand beneath sea surface" .)
