Abandoned Legoland, heading off for the Lifford area (7)
I believe the answer is:
donegal
'the lifford area' is the definition.
(Lifford is in County Donegal in Ireland)
'abandoned legoland heading off' is the wordplay.
'abandoned' indicates anagramming the letters (the original order is abandoned).
'heading off' means to remove the first letter.
'legoland' with its first letter removed is 'egoland'.
'egoland' anagrammed gives 'DONEGAL'.
'for' is the link.
(Other definitions for donegal that I've seen before include "part of Ireland" , "town and county" , "County of NW?Ireland" , "Ireland's northmost county" , "County of NW Ireland" .)
