Here are a few images from the Reynisfjara, the most well-known and loved black sand beach on the south coast of Iceland near the town of Vík (Vík í Mýrdal).
The basalt pillars you see here are at what I consider the entrance to the rest of the beach, on the side of a cliff called Gardar.
The photographs are credited to Bark River Photography.
Here is the link to a webpage with some more information about the beach, including safety tips for the notoriously treacherous waves and ocean currents: https://guidetoiceland.is/travel-iceland/drive/reynisfjara
It may not be evident from here, but we did have quite an audience at the time of day these were taken.
