Blue Lagoon complex, located between Grindavik and Keflavík, is a geothermal spa in south western Iceland. Dramatically colored in shades of deep blue, silver, gray and black, this renowned spa destination offers a striking spectacle. Set in a lava field on the Reykjanes Peninsula, the spa is fed by steaming hot waters from the nearby Svartsengi geothermal power station. Explore a massive complex of silvery towers, changing rooms, restaurants, sauna and bar, dotted with hot-pots and steam rooms. A tumbling, piping hot waterfall provides spa-goers with a powerful hydraulic massage. The complex also houses a hotel, if you’re planning on an overnight visit.
