Travel in part of Hebrides (4)
I believe the answer is:
ride
'travel' is the definition.
(riding is a kind of travelling)
'part of hebrides' is the wordplay.
'part of' indicates a hidden word.
'RIDE' can be found hidden inside 'hebrides'.
'in' is the link.
(Other definitions for ride that I've seen before include "Travel, by horse say" , "Travel on (a bicycle)" , "Go by bicycle" , "Sit on (a horse/vehicle)" , "Take journey" .)
