Travelling around the north, happily showing largesse (12)
I believe the answer is:
philanthropy
'largesse' is the definition.
(thesaurus)
'travelling around the north happily' is the wordplay.
'travelling around' indicates an anagram.
'north'+'happily'='northhappily'
'northhappily' anagrammed gives 'PHILANTHROPY'.
'showing' is the link.
(Other definitions for philanthropy that I've seen before include "Benevolence towards humanity" , "The donating of money to good causes" , "Generous deeds" , "Benevolence to others" , "Promotion of others' welfare" .)
