Hrunalaug

Hrunalaug near Flúðir in the South Iceland lowlands is a small, naturally warm bicarbonate hot pool fed by a geothermal spring in a grassy hollow beside a small stream, accessible via a short track from the road — one of Iceland's most beloved 'hidden' hot pots that balances intimacy and accessibility in a country where wild swimming in geothermal water is a national cultural practice. The pool accommodates only a handful of bathers at once, maintaining the sense of natural intimacy that makes Hrunalaug feel like a personal discovery even as its fame has grown through social media and travel guides. Located in the Flúðir area, known for its geothermal greenhouses producing tomatoes and cucumbers year-round using volcanic heat, Hrunalaug represents Iceland's tradition of small, unembellished community hot pots that exist as practical amenities in a geothermally rich landscape.
