Las Gredas de Bolnuevo 🏜️, also known as the Enchanted City 🏰, are stunning sandstone formations in Bolnuevo, Spain 🇪🇸. Shaped like mushrooms 🍄 and vertical pillars 🗿, these unique structures were sculpted by wind and water 🌬️💧 over millions of years. The yellowish hue comes from the high sand content in the clay, which dates back to the Pliocene period 🕰️. Protected by a fence now, these formations are a must-see for nature lovers 🌿 and Instagrammers 📸 alike.
