A reactivated Mesozoic caldera is located in Sai Kung, Hong Kong, the central part of which contains a large area of exposed rhyolitic columnar joints, which form a landscape of stone columns. It is characterised by an extensive distribution of regular and large columns. Many small islands are composed of this type of column, with features such as sea caves, sea arches and a columnar one-line sky over the sea. Many columns on these islands have sunk into the sea to become submerged columns. The features are so amazing that Hong Kong has preserved this spectacular landform. In 2009, it was designated as a national geopark, and it became a global geopark in 2011 (Fig. 1).
