Reynisfjara

Reynisfjara is a popular black sand beach in southern Iceland near the town of Vík í Mýrdal. ^[1][2] It is part of the Katla UNESCO Global Geopark. ^[3][4][5][6]

Hálsanefshellir Cave with its basalt columns is located at the eastern end of the beach, and in the west is Dyrhólaey promontory. The Reynisdrangar Sea Stacks are also located here. ^[7][8] Eyjafjallajökull volcano is visible from the beach.

Conditions on the beach vary greatly and can change quickly. ^[9][10]

Reynisfjara beach attracts large numbers of visitors year-round due to its striking black sand and dramatic basalt sea stacks, but it is also the site of unpredictable sneaker waves that can surge far inland without warning. Because many tourists focus on photography and overlook hazard signage, these powerful waves—generated by the convergence of swell trains over a submerged offshore ledge—have led to at least twelve serious emergency rescues and five fatalities since 2007.^[11]

In response to the ongoing risk, Icelandic authorities and local stakeholders have proposed and begun implementing a suite of interventions.

The beach has a warning system with condition-dependent safety zones for cautioning visitors during hazardous conditions, such as sneaker waves. ^{[12][13][14][15]} This system was installed following fatal accidents.

Safety measures include the placement of highly visible, multilingual warning signs with pictograms; the development of a real-time wave-forecasting system linked to warning lights; and the consideration of daily visitor allowances and nominal entrance fees to fund safety infrastructure. Enhanced coordination between the Icelandic Association for Search and Rescue, the Icelandic Road and Coastal Administration and tourism operators aims to improve hazard information via social media, guide books and on-site personnel, thereby raising awareness of sneaker wave dangers while encouraging more sustainable patterns of visitation.^[11]
