Living Walks – Madeira Islands, Portuguese Arquipélago da Madeira, archipelago of volcanic origin in the North Atlantic Ocean, belonging to Portugal. It comprises two inhabited islands, Madeira and Porto Santo, and two uninhabited groups, the Desertas and the Selvagens. The islands are the summits of mountains that have their bases on an abyssal ocean floor. Administratively, they form the autonomous region of Madeira. The regional capital, Funchal, is located on Madeira Island.
Madeira Island, the largest of the group, is 34 miles (55 km) long, has a maximum width of 14 miles (22 km) and a coastline of about 90 miles (144 km), and rises in the centre to Ruivo Peak (6,106 feet [1,861 metres] above sea level). The greater part of the interior above 3,000 feet (900 metres) is uninhabited and uncultivated; communities of scattered huts are usually built either at the mouths of ravines or upon slopes that descend from the mountains to the coast.
