Reykjaböð Hot Springs

Reykjaböð Hot Springs is a modern geothermal hot springs and bathhouse in Hveragerði, South Iceland, at the foot of Reykjadalur valley. It combines naturally heated water, mountain views, sauna rituals, cold plunge bathing and modern facilities about 35 minutes from Reykjavík.

Story

At the mouth of Reykjadalur — the "Steam Valley" that has drawn bathers up its hot river for generations — Reykjaböð opened on 5 September 2026 as Iceland's newest purpose-built geothermal bathing destination. The lagoon holds untreated geothermal water drawn from the ground beneath Hveragerði into a 900 m² pool kept around 37–40°C, looking up toward the same steaming hillsides that made this valley famous long before any spa stood here. Beyond the lagoon, the architecture leans into restraint rather than spectacle: low, greenhouse-inspired buildings sit tucked into the land, echoing Hveragerði's century-old identity as Iceland's geothermal greenhouse town, while a ten-room bathhouse sequences guests through contrasting saunas, cold plunges and steam rooms in a ritual borrowed from Japanese onsen and Nordic bathing tradition alike. It is, in effect, an engineered and considerably more comfortable version of the same warm water that hikers have soaked in barefoot a short walk further up the valley for decades.
