The Diamond Beach is a strip of black sand belonging to the greater Breiðamerkursandur glacial plain, located by Jökulsárlón glacier lagoon on the South Coast of Iceland.
Those who join certain guided packages, such as this 6-Day Summer Ring Road Tour, will have an opportunity to explore it, as will those on self-drive excursions such as this 7-Day Winter Road Trip. It can also be accessed from the Ring Road by those who rent a car.
At the Diamond Beach, the icebergs which fill the Jökulsárlón glacier lagoon wash up on shore, creating a stark contrast with the volcanic black sand. This beautiful display makes it a favourite location for photographers and nature lovers. Wildlife enthusiasts also frequent the site as many seals call the beach home, and it is one of the best places in the country to see orcas from the shore.
Breiðamerkursandur is a glacial outwash plain located in the municipality of Hornafjörður. The sand stretches approximately 18 kilometers along Iceland’s South Coast, more specifically from the foot of Kvíárjökull Glacier to the famed glacier lagoon Jökulsárlón. This lagoon sits by the foot of Breiðamerkurjökull Glacier.
Both glaciers are among the 30 outlets of Vatnajökull, Europe’s largest ice cap and the central feature of the Vatnajökull National Park. Many of these are seen en route to the Diamond Beach as you travel along the South Coast.
The outwash plain was formed when three of Vatnajökull’s outlet glaciers, Breiðamerkurjökull, Hrútárjökull and Fjallsjökull, flowed forward due to volcanic activity. This ground the rocks of the underlying surface, creating and pushing forward the glacial sediments.
Such sand plains are a common part of the Icelandic landscape, due to the island being volcanically active as well as boasting numerous ice caps.
The glacier lagoon and Diamond Beach are fantastical sites; however, the rate of their expansion is, unfortunately, a consequence of climate change as the glaciers retreat. With the rate that the caps are melting, there may be no ice left at either site within decades.
Jökulsárlón glacier lagoon is one of the most famed and visited attractions in Iceland. Floating on the lagoon are countless icebergs that have broken off the resident glacier, creating an ever-changing scenery of incredible beauty.
The river Jökulsá connects the lagoon to the Atlantic Ocean, meaning that these icebergs eventually drift out to sea where they are polished by the waves before floating back to the black sands of Breiðamerkursandur. The name ‘Diamond Beach’ thus comes from the white ice on the black sand appearing like gemstones or diamonds, as they often glisten in the sun.
Safety at the Diamond Beach
The Diamond Beach is a safe place for any responsible traveler; unlike Reynisfjara, another South Coast black sand beach, sneaker waves and rip currents are not notorious for whisking unwitting tourists out to sea. However, there are still dangers to consider.
The main one of these is the icebergs themselves. Under no circumstance should you climb upon an iceberg, due to their slippery surfaces and sharp edges.
This is especially the case if the iceberg is at all in the water, as it could flip and trap you underneath, or else be pulled out to sea by a current with you on it.
The risk of injury and illness in the form of hypothermia is so great that extortionate fines exist to deter any ‘rebels’ looking for a thrill-seek. These have only come about due to serious incidents, to protect not only tourists at the lagoon but also guides and staff who may feel obligated to embark on a dangerous rescue if they see someone at risk.
