Leads around the valleys (5)
I believe the answer is:
dales
'the valleys' is the definition.
(dale is a kind of valley)
'leads around' is the wordplay.
'around' indicates an anagram.
'leads' is an anagram of 'DALES'.
(Other definitions for dales that I've seen before include "Yorkshire valleys" , "(North England) valleys" , "Leads into poetic valleys" , "Open river valleys in hilly areas" .)
