The Retreat at Blue Lagoon, Grindavík, Iceland

Set within a lava field on Iceland’s Reykjanes Peninsula, The Retreat at Blue Lagoon feels less like a hotel and more like a carefully hidden world. 

With 60 suites, this modern resort dissolves into its surroundings — moss-covered rock, dark stone walls, and milky geothermal waters drifting quietly past floor-to-ceiling windows.

It’s an immersive, elemental escape where architecture, nature, and stillness exist in perfect balance.

What Makes It Special

• 60 expansive suites, each with private terraces overlooking lava fields or lagoon waters.
• Exclusive access to the Retreat Lagoon, quieter and more secluded than the public Blue Lagoon.
• Subterranean spa spaces, carved into volcanic rock for deep, sensory calm.
• Michelin-starred Moss Restaurant, showcasing Icelandic ingredients with precision and restraint.
• Minimalist Nordic architecture, designed to disappear into the landscape.
• A rare sense of silence and privacy, despite proximity to one of Iceland’s most famous sites.

A Day at The Retreat at Blue Lagoon

Morning

Wake to soft, mineral-scented air and slip directly into the warm geothermal waters of the Retreat Lagoon. Steam rises slowly as pale blue water contrasts against black lava and moss. Breakfast follows quietly, almost ceremonially.

Afternoon

Spend hours drifting between the lagoon, spa rituals, and your suite. Time stretches here — treatments use silica, algae, and minerals drawn directly from the earth beneath you.

Evening

Dine at Moss, where the flavors are as restrained and precise as the surroundings. As darkness falls, the lava fields settle into deep silence, broken only by water moving gently around stone.

Night

Your suite becomes a cocoon — muted light, raw textures, and the distant glow of geothermal steam outside the glass.

Insider Tips for The Retreat at Blue Lagoon, Grindavík, Iceland

• Book early if you want a lagoon-view suite — these are the most sought-after and can sell out fast, especially in peak summer or northern-lights seasons.
• The subterranean Retreat Spa is exceptional and included with your stay.
• Reservations for specific spa treatments, massages, or float therapy (often extra cost) are recommended well in advance — these fill up quickly. 
• Make restaurant bookings before arrival, especially for Moss — it’s one of the hotel’s signature draws and books out, particularly on busy travel dates. 
• If you’re visiting in winter months, ask about Northern Lights wake-up calls — staff will alert you if aurora activity is visible.
