Bluff Island


A Sea Cliff full of Hexagonal Prisms

Bluff Island, Basalt Island, Wang Chau, etc. are known as Ung Kong Group. Along Bluff Island by boat, you will see the spectacular sea cliff full of hexagonal prisms, gravel beaches formed by collapsed columns, as well as dark-grey basalt dikes that have intruded along columnar joints in the nearly upright hexagonal rock columns.
