A Spa of the Volcanic Earth

Carved into an 800-year-old lava flow, the spa at the Retreat brings you into harmony with nature and the timeless powers of the Blue Lagoon’s revitalizing waters.

The Lagoon

Unlocking a new experience of the Blue Lagoon, the mineral-rich water surrounding the Retreat circulates through a terraced concourse of lava. With its canyons, corridors, and open spaces, this geothermal reservoir brings intimacy, serenity, and discovery. 

An Extraordinary Journey

Transporting your mind and body to new dimensions of peace and rejuvenation, the spa journey takes you through an underground realm of inspiring design and radiant wellness.

Into the Earth

You move ever deeper through lava sanctuaries encompassing endless possibilities: dry heat, steam heat, massage, fire, a panoramic viewing deck, a cold air well, and the mineral-rich waters of the Retreat lagoon.

The Blue Lagoon Ritual

The journey culminates with the Blue Lagoon Ritual—an exhilarating cycle of wellbeing where you experience the treasures of geothermal seawater: mineral salt, silica, and algae.

Energized by nature and catalyzed by science, the ritual brings your mind and body to new horizons of serenity, radiance, and rejuvenation.


Blue Lagoon algae is extraordinarily dynamic. It renews, nourishes, and moisturizes your skin—opening the door to an enduring, youthful glow.

Mineral salt

The Blue Lagoon’s uniquely potent array of mineral salts have revitalizing effects on your mind and body—exfoliating your skin and stimulating your circulation.


Silica, the Blue Lagoon’s iconic white mineral, cleanses and strengthens your skin—giving you a fresh, pure, radiant appearance.
