With a total land area of just 21 sq km, Macau consists of a narrow peninsula and the islands of Taipa and Coloane. However, with its ever-growing popularity with tourists and entrepreneurs alike, Macau is growing and extensive land reclamation projects are underway to accommodate them all. The terrain has low hills and on the west of the peninsula, one of the main channels of the Xi He (West River) empties into the South China Sea.
