The Retreat at Blue Lagoon Iceland
Brutalist-Scandi minimalism rooted in its lava-field setting. Concrete, timber, and slate inside; steam, moss, and blue water outside. No TVs. Robes are the default daytime attire. Quiet and intentional — the kind of place where guests slow down by design.
Book Moss Restaurant and spa treatments well before arrival — both fill up fast, especially on weekends
Why It Matters
It is the only hotel with direct access to the Blue Lagoon's private, guests-only geothermal lagoon — sourced from the same healing waters as the famous public lagoon but without the crowds. Moss Restaurant earned Iceland's first hotel Michelin star in 2023, retained it in 2024 and 2025. The subterranean spa — tunnelled into 800-year-old lava rock — covers over 4,000 sqm and includes a 900-sqm private lagoon.
The Retreat opened in 2018 as the only five-star hotel at Iceland's Blue Lagoon, carved directly into an 800-year-old lava field on the Reykjanes Peninsula. Sixty suites circle a private, guests-only geothermal lagoon — the same mineral-rich water as the public Blue Lagoon, but far quieter. The hotel earned One Michelin Key and houses Iceland's first hotel restaurant with a Michelin star (Moss). Designed by Basalt Architects, it runs entirely on geothermal energy and holds B Corp Certification.
Where You'll Stay
5 room types available
Blue Lagoon Suite
The hotel's most expansive accommodation — a palatial two-story, two-bedroom sanctuary with its own private lagoon, private spa (steam room and sauna), butler service, kitchen, and dining area. Floor-to-ceiling windows on both levels open to panoramic views of water and moss-covered lava. Select Retreat Spa treatments can be delivered in-suite. Maximum occupancy 4 adults. Rates are on request.
230 sqmLagoon Suite
The step-up suite that delivers what many guests come for: a two-room sanctuary with a private stretch of the geothermal lagoon directly accessible from the lower-level terrace. Floor-to-ceiling windows dissolve the boundary between inside and out. Two-night minimum stay. Children under 9 not permitted.
King · 60 sqmLagoon View Junior Suite
Same footprint and fixtures as the Lava View Junior Suite but with floor-to-ceiling windows oriented toward the milky-blue geothermal lagoon. Serene blue water fills the frame. Ground floor with a small private terrace. Also restricted to guests aged 9+ due to water proximity.
King · 40 sqmLava View Junior Suite
The entry-level suite faces the lava fields rather than the lagoon — a rawer, more geological view. Ground floor with a 10 sqm private terrace directly onto the lava flows. Floor-to-ceiling windows, wooden panelling, freestanding bathtub. Same size and finish as all Junior Suites; the difference is purely the view. Children under 9 not permitted due to water adjacency.
King · 40 sqmMoss Junior Suite
The upper-level Junior Suite with a 28 sqm private balcony and a horizon view across the volcanic frontier — no direct lagoon view, but the elevated vantage gives sweeping panoramas ideal for Northern Lights watching. Slightly larger than the Lava and Lagoon View suites. Same interior palette of timber, floor-to-ceiling glass, and a freestanding tub.
