Spain's Basque Country is home to one of the geological wonders of the world. Along the Bay of Biscay coast near the town of Zumaia is one of the longest continuous rock formations on earth. The formation runs for about 8 km (around 5 mi.), with Zumaia roughly in the middle. In this drone video by dronostia, you'll get an aerial view of the Itzurun Beach, which lies on one side of Zumaia. The beach is also home to the San Juan de Gaztelugatxe islet, kinown to Game of Thrones fans as Dragonstone.
