About Kat O#

Kat O is an inhabited island in Hong Kong’s North District, commonly known in English as Crooked Island. It retains several traditional villages and coastal features typical of Hong Kong’s outlying islands.

Kat O has a long history as a fishing and shipbuilding community within the waters of the northeastern New Territories, with village life and temples reflecting maritime traditions. It has remained relatively rural compared with Hong Kong’s urban areas.

Kat O sits off the northeastern coast of Hong Kong’s New Territories, within the North District administrative area. It is reached by small ferry services from mainland piers and lies among other outlying islands in the region.

  • Also called Crooked Island: Often referred to in English as Crooked Island; it is part of Hong Kong’s North District and retains traditional fishing-village character and coastal walking routes.
  • Access: Accessible by small ferry services that connect it with piers on the northern New Territories; facilities on the island are basic and suited to day visits or short stays.

What to See#

  • Kat O Village: A mixed cluster of traditional village settlements on the island with narrow lanes and houses centred on small piers and shorelines used historically by fishermen.
  • Tin Hau Temple: A coastal temple commonly found on outlying islands of Hong Kong, dedicated to the sea goddess and used historically by local fishing communities.
