The Itsaslur Greenway, which clings to the cliffs of the westernmost coast of Bizkaia, is a spectacular trail. The old route of the Kobaron to Campomar mining railway has become an elevated seafront promenade and an educational, open air itinerary.

The Greenway offers sweeping views of the Cantabrian shoreline and passes sites of industrial archaeological remains which hark back to the mining activity of bygone centuries. A number of information panels tell us about the fauna and the flora, the ancestral tradition of seaweed gathering and, of course, the old iron ore workings.
