La Aldea de San Nicolás is located about 38 km southwest of the island capital Las Palmas. It is situated among forested mountain valleys overlooking the Atlantic, and most families work on the tomato-farms, as well as growing potatoes and other vegetables and fruits, irrigated by reservoirs that collect winter rain. Tourism is also a significant industry, though not as much as in the South of the island.
