Skating sites (5)
I believe the answer is:
rinks
'skating sites' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rinks that I've seen before include "Surface for ice- or roller-skating" , "Skating venues" , "Surfaces for skaters" , "Skating surfaces" , "Surfaces for ice- or roller-skating" .)
