Spain is full of stunning natural settings. Nevertheless, there are some places that are especially fascinating. One of these is the Flysch Route on the coast of the Basque Country, northern Spain. Come and accompany us on a journey along the coast of Guipúzcoa and admire one of the most spectacular areas of cliffs you have ever seen, which also conceal 50 million years of history. Come and discover this whim of nature.Only occasionally do we have the privilege of seeing real natural treasures. So, if you travel to the province of Guipúzcoa (in the Basque Country), we would recommend you take a boat trip to the coastal towns of Mutriku, Deba and Zumaia. There you can do what is known as the ?Flysch Route?: several kilometres of rugged cliffs that lead down into the sea, formed through the erosive action of water and movements of land over the course of 50 million years. These rocks have always been of interest to geologists on account of their fossil remains. Now it is your turn to discover them.
