Got in trouble around rocky height back in cave (6)
I believe the answer is:
grotto
'cave' is the definition.
(grotto is a kind of cave)
'got in trouble around rocky height back' is the wordplay.
'in trouble' indicates an anagram.
'around' means one lot of letters goes inside another.
'rocky height' becomes 'tor' (I've seen this before).
'back' is a reversal indicator.
'tor' reversed gives 'rot'.
'got' is an anagram of 'gto'.
'gto' enclosing 'rot' is 'GROTTO'.
'in' acts as a link.
(Other definitions for grotto that I've seen before include "A picturesque cave as in Lourdes (6)" , "Type of cave, often with religious significance" , "It's left on Dec 24 by Santa and his reindeer" , "Ornamental cave" , "Cavern" .)
