Sierra Maestra is a mountain range that runs westward across the south of the old Oriente Province in southeast Cuba, rising abruptly from the coast. The Sierra Maestra itself is located mainly in Santiago de Cuba Province and in Granma Province. Some view it as a series of connecting ranges, which joins with others extending to the west. The Sierra Maestra is the highest area of Cuba. It is rich in minerals, especially copper, manganese, chromium, and iron. At 1,974 m, Pico Turquino is the range's – and the country's – highest point.
