What are the Gredas of Bolnuevo?
The name comes from the clay-like material from which they are formed, which is a kind of sandy clay traditionally used in crafts such as pottery. The compact sand grains in this material have resulted in formations that have been sculpted by the wind, sand and sea over thousands of years. This has been even more pronounced as these features are located in the coast area and are very exposed to the strong forces of the wind and waves. The Gredas of Bolnuevo are the perfect backdrop for the beautiful setting of the Bolnuevo beach.Millions of years ago, the Gredas were under the sea. With the passing of the centuries, the sea level has fallen, leaving them exposed and unprotected from the wind and other natural phenomena that have shaped them. As a result, the mushroom-shaped rocks of this enchanted city will always be changing.
