Diamond Beach, located near Jökulsárlón glacier lagoon on Iceland's South Coast, is a stunning strip of black sand adorned with icebergs that have washed ashore. The contrast between the dark sand and glistening ice makes it a favorite spot for photographers and nature enthusiasts. If you're lucky, you can also spot seals and orcas from the beach. The best time to visit the diamond beaches are in the winter, at sunrise or sunset.
