Where the crust of Iceland splits open and the earth's own heat rises to meet the snow.
A basalt scar vents steam through a storm that never quite stops moving.
Twelve rooms buried in snow, built around the one thing this land gives freely.
39°C, silica-clouded, fed by a borehole 2,100 metres down. This is the reason to come.
Most guests arrive by the coastal road from Akureyri. This is what unfolds once the storm gate closes behind you.
Boots off at the basalt entry hall; a warm cup of skyr-and-birch tea while the retreat log takes your borehole briefing.
First entry to the lagoon proper — a slow acclimation lap along the shallow shelf where the water runs coolest, 37°C.
A guided walk to the working fissure field, where the same heat warming your room vents raw from the rock.
Dinner service faces the lagoon's steam line, lit only by the water's own pale glow after dark.
The pools stay open until 1am. In clear weather, the aurora reflects directly on the milk-blue surface.
Every experience here traces back to the same borehole. Nothing is decorative — the geology is the design.
A three-pool gradient from 37° to 41°C, each drawn from a different depth of the same well.
A single-room sauna cut into solid rock, heated by a vent shaft rather than an element.
Guided evening walks to the active steam field, 20 minutes on foot across packed snow.
Iron-rich clay drawn from the lagoon floor, applied lakeside and rinsed in the shallows.
A meltwater trough at 4°C, set directly against the warm shelf for contrast bathing.
An unheated viewing platform above the steam line — the clearest aurora sightline on site.
"We stopped talking somewhere in the second pool. The water does that — it just quiets you."

The retreat sits above a single fissure swarm. Each marked point feeds a different part of the site.
The primary borehole. Feeds the main lagoon directly and runs the warmest of the five sites on record.





A confirmation will follow by email within the hour. The lagoon will be exactly 39°C when you arrive.
