Blue Lagoon Verified listing

The Blue Lagoon is Iceland’s most famous geothermal spa, located in a lava field near Grindavík on the Reykjanes Peninsula, about 45 minutes from Reykjavík and just 20 minutes from Keflavík International Airport. Known for its striking milky-blue waters and otherworldly surroundings, the lagoon is rich in silica, algae, and minerals that are believed to nourish the skin. The water is naturally heated to a soothing 37–39°C (98–102°F), making it a year-round destination regardless of Iceland’s unpredictable weather.

Beyond soaking in the iconic waters, visitors can enjoy in-water silica face masks, a swim-up bar, and optional spa treatments. The Blue Lagoon also features upscale facilities such as the Retreat Spa—a luxury experience with private lagoons, steam rooms carved into lava rock, and exclusive skincare rituals. Two on-site hotels and several restaurants, including the acclaimed Moss Restaurant, allow guests to turn a day visit into a full wellness retreat. The lagoon uses water sourced from the nearby Svartsengi geothermal power plant, highlighting Iceland’s blend of natural beauty and sustainable innovation.

Due to its popularity, advance booking is essential, especially during peak tourist seasons. Entry packages vary, from basic access with a towel and mask, to premium options that include robes, drinks, and spa upgrades. Despite being one of Iceland’s most touristy attractions, the Blue Lagoon remains a must-visit for first-timers and spa lovers alike—offering an unforgettable sensory experience in a surreal and tranquil landscape.
