The most beautiful black sand beach in the world is located in Iceland, and it is called 'Reynisfjara' in Icelandic.

A black sand beach is something that cannot be found in many places on Earth. The pitch black sand strikes a perfect contrast against the white foam of the waves and the blue water.

Reynisdrangar are basalt sea stacks situated under the mountain Reynisfjall near the village "Vík í Mýrdal" in southern Iceland. It is framed by a black sand beach that was ranked in 1991 as one of the ten most beautiful non-tropical beaches in the world. In 2021 Reynisfjara was rated the 6th best beach in the world.

Legend says that the stacks originated when two trolls dragged a three-masted ship to land unsuccessfully and when daylight broke they became needles of rock.

Reynisdrangar appears several times throughout Netflix's Icelandic original series "Katla", and is particularly significant to the series' protagonist Gríma as the site of her mother's death.
