Einireykir — 'One Steam' or 'Single Smoke' — is a geothermal spring or vent in Iceland whose name captures the characteristic visual signature of volcanic activity: the single plume of geothermal steam rising into the cold Icelandic sky from a solitary hot spring or fumarole. Such individually named vents and springs are a distinctive feature of Icelandic geothermal culture, reflecting the close observation and personalised relationship that Icelanders have always maintained with the volcanic landscape they inhabit. Einireykir forms part of the rich vocabulary of named geothermal features that makes Iceland's thermal landscape one of the most humanised volcanic environments on earth.
Insider tip — Einireykir is a low-temperature geothermal area in the Dalir district of West Iceland, where warm ground water surfaces at comfortable bathing temperatures. The name translates roughly to Lonely Smoke, alluding to the wisps of steam that drift off the pools on cool mornings. The setting is rural and largely undeveloped, offering a peaceful soak with views across lava-strewn farmland. Locals have historically used the warmth for laundry and small-scale bathing.
