Iceland's beaches and mud are actually black, so the cloudy Iceland is a special magic. Because Iceland has many active volcanoes, the black sand is derived from volcanic lava. Although there are many black sand beaches in Iceland, this black sand beach is more famous because of the basalt columnar joints on the beach. The basalt is formed in a volcanic eruption, and the magma is condensed after it has cooled. These uneven stone pillars are incomparably regular shapes, just like artificial carvings, like the scenes in anime. The two reefs on the sea are also from volcanic lava, very magical. The sky suddenly changed again, and the waves rolled over, more like a magical world. It is recommended to wear bright clothes, which will create a strong visual impact with the black background.
