Official Blue Lagoon: Retreat Spa & Private Changing Suite

There is visiting Iceland’s Blue Lagoon. And then there is disappearing beneath the lava for five hours. Designed for two, the **Retreat Spa at Blue Lagoon** transforms Iceland’s most famous geothermal experience into something far more private: a subterranean sanctuary carved into the volcanic landscape, with its own lagoon, private changing suite, steam cave, sauna, cold plunge, fireside spaces, and an immersive skincare ritual inspired by the mineral-rich water outside. From the moment you arrive, the pace changes. After an introduction to the spa, you are shown to your **private changing suite for two**, complete with a spacious shower, dry changing area, towels, bathrobes, flip-flops, and Blue Lagoon skincare amenities. Then step into the lava. A dramatic underground concourse leads through the Retreat Spa, connecting a **sauna, steam cave, cold plunge well, fireplace, nesting areas, refreshments, relaxation spaces, and a panoramic viewing deck** overlooking the otherworldly Icelandic landscape. But the heart of the experience is the **Retreat Lagoon**. Filled with the same unmistakable blue geothermal water as the main Blue Lagoon, this private lagoon offers a quieter, more exclusive way to experience it. Slip into the warm water, order your included drink, and allow the volcanic landscape and milky-blue water to become your surroundings for as long as you like. With five hours of spa access, there is no reason to hurry onward. One of the experience’s signature moments is the **Blue Lagoon Ritual**, a self-applied full-body skincare journey incorporating some of the ingredients most closely associated with the destination. Move through a sequence of **mineral salt scrub, Silica Mud Mask, Algae Mask, and nourishing face and body oil**, applying each element yourself as part of the ritual. Silica, algae, minerals, geothermal bathing, sauna, and other elements of the Blue Lagoon experience are associated with various cosmetic and wellness claims. Specific therapeutic or transformative outcomes should not be assumed. Their appeal here is also beautifully sensory: mineral textures against the skin, geothermal warmth, steam rising from blue water, and the stark contrast of ancient black lava surrounding it all. Your Retreat Spa access also includes the **main Blue Lagoon**, allowing you to experience both sides of the destination if you wish. When hunger eventually interrupts the soaking, the Spa Restaurant is available for dining at additional cost. Its seasonal menu focuses on fresh ingredients and lighter dishes, served against expansive views of geothermal water and centuries-old lava. Reservations are not required, making it easy to fit lunch naturally into your spa day rather than scheduling the spa around your meal. Then return to the lagoon. Five hours gives you the luxury of repetition: another sauna, another soak, a cold plunge if you choose, time beside the fire, perhaps the main lagoon—and then back into the quiet blue water of the Retreat. **The luxury here is not simply seeing the Blue Lagoon—it is having time and privacy to disappear into it: five hours beneath Icelandic lava, your own changing suite for two, a secluded geothermal lagoon without the main crowds, mineral rituals for the skin, steam and cold water, a drink in hand, and nowhere you need to be until you decide you are finished.** **Best suited for:** Couples, honeymooners, anniversary celebrations, luxury travelers, spa connoisseurs, and Iceland visitors seeking the most immersive and private interpretation of the Blue Lagoon experience. **Experience includes:** Five-hour Retreat Spa access • private changing suite for up to two guests • private Retreat Lagoon access • Blue Lagoon Ritual • sauna • steam cave • cold plunge and relaxation spaces • Blue Lagoon Skin Science amenities • towel • bathrobe • flip-flops • access to the main Blue Lagoon • one drink of your choice. **Dining note:** The Spa Restaurant is available during your Retreat Spa visit without advance reservations, but **food and dining are not listed among the included services and should be treated as an additional expense**.
