Also known locally as Reynisfjara, Vik Beach is one of the top non-tropical beaches in the world. Located along the southern coast of Iceland, you’ll find amazing scenery here, as well as huge basalt sea stacks called reynisdrangar. Its famous dark color is the result of lava from the nearby volcano Katla flowing into the ocean; the basalt lava cooled immediately and shattered, washing back to the shore to form the black sand. The water here is rough, however, and beachgoers are advised to keep a safe distance of 20 to 30 meters from the waves.
