See rubbish leading to cave (6)
I believe the answer is:
grotto
'cave' is the definition.
(I've seen this before)
'see rubbish leading to' is the wordplay.
'see rubbish' becomes 'grot' (I've seen this before**).
'leading' is a charade indicator (letters next to each other).
'grot'+'to'='GROTTO'
(Other definitions for grotto that I've seen before include "Santa's cave" , "Attractive natural, or artificial, cave" , "Cavern" , "Artificially or naturally ornamented cave" , "Fancy cave" .)
