Wander aimlessly around Low Countries at first, then Hungary (5)
I believe the answer is:
mooch
'wander aimlessly' is the definition.
(I've seen this before)
'low countries at first then hungary' is the wordplay.
'low' becomes 'moo' ('moo' can be a synonym of 'low').
'at first' says to take the initial letters.
'then' says to put letters next to each other.
'hungary' becomes 'h'.
The initial letter of 'countries' is 'c'.
'moo'+'c'+'h'='MOOCH'
'around' acts as a link.
(Other definitions for mooch that I've seen before include "bum" , "Loiter in bored fashion" , "Wander aimlessly" , "Walk aimlessly around" , "Loiter in bored manner" .)
