To the sheltered side (7)
I believe the answer is:
leeward
'to the sheltered side' is the definition.
(leeward means on the side protected from the wind)
This is the entire clue.
(Other definitions for leeward that I've seen before include "Quarter towards which the wind blows" , "Draw eel (anag.)" , "On sice turned away from wind" , "Of ship, on side turned away from wind" , "WI island group" .)
