Dragon tails trail to the sea

These dragon tail-like structures that stretch into the Bay of Biscay on the Basque Coast of northern Spain are part of one of the most unique and remarkable geological formations on the planet. It’s a wonderland for geologists, and for people who just like looking at cool rocks. Guided tours of the Basque Coast Geopark allow visitors to discover 60 million years of uninterrupted geological history.
