Goes like happy little girls on excursions (5)

I believe the answer is:

trips

I'm a little stuck... Click here to teach me more about this clue!

'excursions' is the definition.
(I've seen this in another clue)

I don't understand the remainder of the clue.

(Other definitions for trips that I've seen before include "Stumbles or triggers" , "Journeys or excursions" , "good experiences" , "Outings" , "Stumbles on short journeys?" .)

I've seen this clue in the Evening Standard.
