Bluff Island photo

Located in the southeast of Rocky Harbour, Bluff Island is part of the Ung Kong Group Geo-Area in the Sai Kung Volcanic Rock Region of Hong Kong UNESCO Global Geopark.

Viewed from above, Bluff Island looks like a tortoise with outstretched claws. Rising up all around are tiers of rhyolite. In the southeast of the Island lies the 140 m high sea cliff which is the highest one in Hong Kong, and in the south is the Candle Cave, a famous sea arch with a height of 24 m. Renowned for its diving sites, the Island is a magnet for divers.


Bluff Island is not accessible by public transport. You may arrange your own vessel.
