Three main routes to Troodos were closed on Monday afternoon to unequipped private vehicles following heavy snowfall, police said.
The Karvounas-Troodos, Platres-Troodos and Prodomos-Troodos roads remain open only to vehicles fitted with snow chains or four-wheel drive.
Dense fog has reduced visibility across the Troodos area.
Police urge drivers to exercise particular caution, maintain safe distances from other vehicles and keep their headlights on.
