Journey or excursion (4)
I believe the answer is:
trip
This clue is a double definition.
'journey' is the first definition.
(I know that journey is a more specific form of the action the trip)
'excursion' is the second definition.
(a trip is an excursion or outing)
(Other definitions for trip that I've seen before include "holiday" , "Jaunt" , "A short journey - stumble on it" , "Set off for" , "Tour; slip" .)
