Piste (3,3)
I believe the answer is:
ski run
'piste' is the definition.
(a piste is a type of ski run)
This is the entire clue.
(Other definitions for ski run that I've seen before include "Snow-covered slope" , "A trail for winter sportsmen" , "Recreational snow slope" , "Boggy, swampy" , "cold course" .)
