Field Trip on the Trans-Pyrenean geological road

This is the first international geological road crossing the French & Spanish Pyrenees. It has been jointly developed by a French Organization called “Geoval” and two Spanish Organizations called “Geoambiente”and “GeoTransfert”. This road is a wonderful way to discover the geological heritage of both the Aspe Valley and Upper Aragon. This 200 Kms road records the fabulous story of the formation of the Pyrenees through 400 millions years, which have determined the actual aspect of the Pyrenees and the way of life of its local people.

The itinerary consists of 25 main spots/sites along the road, easily accessible, with incredible views and boards in both French and Spanish which offer a very good and original illustration of the different views and rocks.

This 200kms trip illustrates, step by step, the formation of the Pyrenees: from the sediment settling in seas that have now disappeared, to the erosion of the valleys by the floods, going through the deformation of rocks and the action of the glaciers.

For this course, this itinerary starts in Belair with a Panoramic view on the Pyrenees, and goes through Oloron Sainte Marie, Mail Arrouy, Defile d’Escot, Fontaines d’Escot, Bedous, Accous to end in Cette-Eygun. Throughout this itinerary, you will be able to discover main rocks of the road as well as the geological history of the Western Pyrenees.
