Built into an 800-year-old lava plain, the Retreat Spa is an exquisite subterranean sanctuary where guests commune with the transformative powers of the volcanic earth. Culminating with the Blue Lagoon Ritual, the spa journey takes you to the heights of wellbeing in the heart of a geothermal paradise.
