3Blue Lagoon Retreat – Iceland

A masterpiece of minimalism and geothermal luxury, the Retreat at Blue Lagoon is one of Europe’s most iconic winter spa sanctuaries. Hidden within a lava field on Iceland’s Reykjanes Peninsula, the resort offers private access to the Blue Lagoon’s mineral-rich waters, famous for their skin-healing properties and ethereal milky blue color. In winter, the contrast is extraordinary—billowing steam rises into icy air while snow blankets the black volcanic landscape.

Guests enjoy exclusive features such as the Retreat Lagoon, an ultra-secluded extension of the main Blue Lagoon, plus a subterranean spa carved directly into volcanic rock. Signature rituals include the three-step silica, algae, and mineral cycle, designed to nourish and restore the skin. Soft lighting, calm architecture, and the surreal Icelandic winter atmosphere create an experience that feels almost otherworldly. For many luxury travelers, it’s the most extraordinary geothermal spa escape in Europe.
