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.
The milky blue water comes from silica, minerals, and algae, a result of the geothermal process. The lagoon sits in a lava field about 13 kilometers from Keflavík International Airport, making it convenient for travelers. Facilities include changing rooms, restaurants, and spa services. Entry requires advance booking, and prices are higher than typical beaches, but the unique experience and reliable safety standards make it popular with families and visitors prioritizing environmental responsibility.
