Levada do Norte, Madeira, island of <a href="http://en.wikipedia.org/wiki/Madeira" rel="nofollow">Madeira</a>, Portugal. Hiking tour "Two levadas near Encumeada pass": Levada das Rabaças and Levada do Norte. Madeira is a Portuguese island in the Atlantic ocean, approximately 1000 km (620 mi) southwest of Lisbon and 700 km (435 mi) west of the Moroccan coast. Situated in a hot spot area, Madeira is of volcanic origin, formed during several eruptive phases, the last of which ended around 6500 years ago. Madeira is a very mountainous island. With an extent of only 57 km (35 mi) from west to east and 22 km (14 mi) from north to south, and with the highest mountain having an elevation of 1862 m (6109 ft), the terrain of the island is mostly very rocky and steep, except for the high plateau Paul da Serra. Madeira is also known as the "island of flowers", although most of the popular "typical" Madeiran flowers (like the bird of paradise flower, the hydrangea, the agapanthus and others) are neither endemic nor native. Some of the genuine Madeiran plants are the "Pride of Madeira" (Echium candicans), Canary Islands Juniper (Juniperus cedrus) and the laurel forests of Madeira (the latter one being listed as UNESCO World Heritage). Madeira is permeated by artificially built water channels called levadas, which distribute the water from the wetter northern half of the island to the agricultural regions of the south. The levadas, mostly built by prisoners or slaves, were cut into the side of the mountains, partly running through tunnels, and enabled for example the cultivation of sugar cane which was the source of the Madeiran wealth during the 15th to 17th century. Today most of the levadas are still in use, not only for irrigation but also for hydroelectricity. Running across the whole island, they provide a wide network of walking paths, making even extremely remote regions of the island accessible to pedestrians, which is one of the reasons for Madeira's popularity as a hiking paradise. Madeira hiking holiday July 2013.
