Amusement park feature (4)
I believe the answer is:
ride
'amusement park feature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ride that I've seen before include "Travel on the back of animal" , "Go by bicycle" , "Take a trip" , "Travel, on horseback, say" , "Go by horse" .)
