In the Ngọc Vừng - Quan Lạn islands itinerary, one will visit Cống Tây Island, which lies at the Bái Tử Long Bay, 40 km away from the Bãi Cháy Tourist Wharf. From Cẩm Phả, express boats will take you 30 minutes or 90 minutes by common boats to reach Cống Tây Island.

Cống Tây Island is considered the Cinderella in a legendary tale. The Cẩm Phả Coal Construction and Port Company built a resort in the island to attract holidaymakers. A system of villas and restaurants lies very close to the beach. Red brick-paved, coconut-lined roads lead from the villas to the beach. Hammocks are available here and there for tourists to relax and view the sea.
