A trip gave you most recreation (6)
I believe the answer is:
voyage
'a trip' is the definition.
(I've seen this in another clue)
'gave you most recreation' is the wordplay.
'most' means to remove the last letter.
'recreation' indicates anagramming the letters.
'gave'+'you'='gaveyou'
'gaveyou' with its last letter removed is 'gaveyo'.
'gaveyo' with letters rearranged gives 'VOYAGE'.
(Other definitions for voyage that I've seen before include "Travel by water" , "tour" , "Journey by air or water" , "Ocean trip" , "See 7" .)
