Levada (Madeira)



A levada is an irrigation channel or aqueduct specific to the Portuguese Atlantic region of Madeira.

History
In Madeira, the levadas originated out of the necessity to bring large amounts of water from the west and northwest of the island to the drier southeast, which is more conductive to habitation and agriculture, such as sugar cane production. They were also used by women in the past to wash clothes in areas where running water was not available at homes. Similar examples can still be found in Iberia, such as some aqueducts in Spain.

In the sixteenth century the Portuguese started building levadas to carry water to the agricultural regions. The most recent were made in the 1940s. Madeira is very mountainous, and building the levadas was often difficult. Many are cut into the sides of mountains, and it was also necessary to dig 25 km of tunnels.

Levadas today
Today the levadas not only supply water to the southern parts of the island, they also provide hydroelectric power. There are more than 1350 mi of levadas and they provide a remarkable network of walking paths. Some provide easy and relaxing walks through beautiful countryside, but others are narrow, crumbling ledges where a slip could result in serious injury or death.

A popular levada to hike is the Levada do Caldeirão Verde which continues as the Levada Caldeirão do Inferno. Altogether it is about 23 mi long. Along both parts there are long sections which may cause hikers to suffer vertigo; and several tunnels for which flashlights and helmets are essential. The Levada do Caniçal is a much easier walk. This levada runs 7+1/8 mi from Maroços to the Caniçal Tunnel. It is known as the mimosa levada because acacias (commonly misnamed mimosas) are found all along the route.
