Bluff Island

About The Site

Bluff Island, also known as Sha Tong Hau Shan or Ung Kong/Ung Kong Chau, is one of Hong Kong’s most popular spots for water sports and other recreational activities.

Snorkeling and diving activities normally take place near Ung Kong Wan (an inner bay at the north of Bluff Island). Sandy bottoms dominate in Bluff Island, and coral communities are mostly concentrated towards the east of the island (towards the left if you’re facing the beach), at about 2 – 6 m. The rich corals provide a natural habitat for many reef fishes here.

On holidays and weekends, Bluff Island becomes extremely busy with a lot of surface traffic, so divers must beware! Ascend at shallow water areas and use your SMB to signal to boats at the surface. Stay alert when ascending and be aware of the surface activity.

A submerged car and an artificial reef were once landmarks of diving at Ung Kong Wan. Over time, these have slowly weathered away and by now have almost completely disappeared.

With so many visitors, it is perhaps not surprising that even underwater, the Bluff Island site is littered with garbage. Sunglasses, dive masks, snorkels, food packaging, and disposable cutlery are some of the most often found items, along with occasional encounters of batteries and even door frames and entire toilet bowls! These are a grim reminder of our impact on nature, and a note for us all to be well-disciplined as users and visitors of the outdoors.

On this note, we hope everyone will come together to love our oceans, and refrain from littering into the sea. Where safety allows, divers may also help clean up by removing the trash found underwater – but do take note to ensure that items have not become homes for marine animals before you displace them, so as to not disturb the wildlife. Thank you for your help!
