Ideal for couples, this Retreat Spa offer gives two guests a private changing suite and five extraordinary hours at this subterranean sanctuary. As you embark on your spa journey, you enter a remarkable concourse of lava rock that leads to endless possibilities: a sauna, a steam cave, a fireplace, a nesting area, a refreshment area, a panoramic viewing deck, a cold plunge well, and the mesmerising waters of the private Retreat Lagoon.

Begin the experience when you check in, where you will get a briefing on the spa area and the best way to enjoy the services. You will then be shown to your private changing suite, which includes a large shower and dry area equipped with towels, dressing gowns, flip-flops, and Blue Lagoon Skincare amenities.

The best place to start is the Retreat Lagoon, filled with the same blue geothermal waters as the Blue Lagoon but without the crowds. Here, you can soak and unwind, order a drink of your choice, and take in the serenity.

The pinnacle of the journey is the Blue Lagoon Ritual—an indulgent cycle of well-being, where you interact with the Blue Lagoon’s transformative elements: silica, algae, and minerals. Enjoy this full-body, self-applied treatment pampering session that includes a salt scrub, the popular Silica Mud Mask, the potent Algae Mask, and nourishing face and body oil by Blue Lagoon Skincare.

Spa Restaurant’s seasonal menu serves light and nourishing meals made from fresh local ingredients. A place of true nourishment, Spa Restaurant offers beautiful, expansive views of the surrounding mineral-rich waterscape and the centuries-old lava. The restaurant makes for a memorable culinary experience before, during, or after your spa journey. No reservations are needed.
