From fjords and lava fields to ice caves and black sand beaches, Iceland is a treasure trove of natural wonders. The volcanic black sand of Diamond Beach, pictured in today's image, sparkles with pieces of iceberg washed ashore from the nearby Jökulsárlón glacier lagoon. The contrast between the clear ice and black sand looks particularly surreal when sunlight hits the ice, making it a must-visit destination on Iceland's south coast.
