Recanted going back around the mountain (4)
I believe the answer is:
etna
'the mountain' is the definition.
(Etna is an example)
'recanted going back around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'going back' is a reversal indicator.
'ante' is hidden in the letters of 'recanted'.
'ante' written backwards gives 'ETNA'.
(Other definitions for etna that I've seen before include "Highest active volcano in Europe" , "Active European volcano" , "It can be scorching" , "Neat kind of European volcano" , "Heating vessel" .)
