About the Beach
What is Blue Lagoon Iceland?
Blue Lagoon Iceland is a geothermal lagoon on Iceland's coastline. It holds the Blue Flag award, which means it meets strict standards for water quality, environmental management, and visitor safety set by the Foundation for Environmental Education.
The lagoon operates year-round, though May, June, and September offer the best weather for swimming. Water temperatures stay warm (around 37-40°C) thanks to geothermal heating, even in winter. Before visiting, check current safety guidelines and operating conditions, as weather can affect access.
