Krauma Baths
Krauma is a geothermal spa opened in 2017, sitting directly beside Deildartunguhver, Europe's most powerful hot spring, in the Reykholt area of West Iceland. Six pools, five warm and one cold, are filled with water drawn from Deildartunguhver and cooled with glacial water from the former Ok glacier. No chemical disinfectants are needed because the water is continuously and naturally replaced by the constant flow from the spring. It is one of the most understated spa experiences in Iceland.
Bathing in Water from Europe's Most Powerful Hot Spring, Mixed with Glacial Cold
Deildartunguhver produces around 180 litres of water per second at close to 100 degrees Celsius, feeding a district heating system that warms homes across Borgarnes and Akranes via a 64-kilometre pipeline. The spring has been harnessed for heating since the 19th century and powered what is thought to be Europe's first geothermal district heating system in the 1920s. Krauma, opened in 2017, takes water directly from this source and cools it by mixing it with cold water from the nearby Rauðsgil river, which originates at the former Ok glacier. The result is five outdoor pools ranging from 37 to 43 degrees Celsius and one cold plunge pool at around 5 to 6 degrees. The pools contain no chemical additives: the sheer volume of the constant natural flow keeps the water clean entirely on its own.
The site is deliberately understated. Volcanic stone and timber, open-air pools, steam baths that use geothermal steam directly from Deildartunguhver, an infrared cabin, and a quiet relaxation room with a fireplace and soft music. You can sit in the warm pools with Deildartunguhver itself steaming and bubbling a few metres away, which gives the experience a grounding sense of where the heat is actually coming from. The restaurant seats 60 indoors and focuses on locally sourced Icelandic ingredients, with a terrace overlooking the valley. Adult admission is around 4,900 ISK, children under 10 enter free, and the site is open year-round. Booking in advance is recommended in summer.
Krauma is on Route 50 near Reykholt, about 97 kilometres from Reykjavik, roughly a 1.5-hour drive. It sits on the Silver Circle route in West Iceland and pairs well with the nearby Hraunfossar and Barnafoss waterfalls (10 kilometres), the Snorri Sturluson historical site at Reykholt (2 kilometres), and the Víðgelmir lava cave (25 kilometres). It makes a natural mid-route break for anyone heading to the Snæfellsnes Peninsula or driving a Silver Circle loop from Reykjavik.
