Geology of Macau for Foreign Visitors

Macau’s geology is mainly composed of granite and other hard igneous rocks formed millions of years ago. These rocks shape the city’s low hills, such as Guia Hill and Coloane, offering natural viewpoints and walking trails for visitors. The coastal landscape includes reclaimed land, which has expanded urban areas over time. Because of its solid bedrock, Macau has stable foundations for high-rise buildings and large resorts. For foreign visitors, understanding Macau’s geology helps explain its hilly scenery, compact layout, and the contrast between natural slopes and modern development.
