The new Montes de Hierro Greenways network is a journey through the underground history of Vizcaya. Because for centuries iron moulded the landscape, the life, and the character of this region, before the alchemy of the Guggenheim museum clad it in shining titanium.

This Greenway network is a must for anyone wishing to discover the roots of our cosmopolitan 21st century Greater Bilbao by following the path of these iron arteries which in bygone days forged the city and its surroundings.

These trails whisper to their travellers a mute testimony from centuries gone by, relating legends from the Roman Empire  to the Industrial Revolution and revealing like an open book all the secrets of the men and women of iron who were behind them.
